The reaction mixture was diluted with EtOAc and washed with H2O and brine. The organic layer was dried over MgSO4 and concentrated in vacuo to give 2, 4-dichloro-6-phenylpyrimidine as a solid (1.35 g), which was used without further purification in the next step.As shown in Figure 3-step i, a mixture of phenylboronic acid (1.22 g), 2, 4, 6-trichloropyrimidine (compound 1011), tetrakis(triphenylphosphine) palladium(O) and 2N sodium carbonate (15 mL) in DME (25 mL) was heated at 80 0C overnight. After cooling to it, addition of water (30 mL), extraction with dichloromethane (3 x 20 mL), drying and evaporation, purification by column chromatography (SiO2, 10-20% ethyl acetate in hexane) afforded the desired product, 6-phenyl-2, 4-dichloropyrimidine (compound 1012) (0.544 g). As shown in Figure 3-step ii, compound 1012 (0.34 g) was mixed with (, S)-2-amino-N-(2, 2, 2- trifluoroethylpropanamide (0.3 g) and diisopropylethylamine (0.63 mL) in isopropanol (5 mL) and the reaction mixture heated at 80 0C overnight. Evaporation gave a residue, which after aqueous workup and purification (SiO2, 20% ethyl acetate/hexane) produced 2-(2- chloro-6-phenyl-pyrimidin-4-ylamino)-nu-(2, 2, 2-trifluoro-ethyl)propionamide (compound 1013) (0.165 g). As shown in Figure 3-step iii, compound 1013 (29 mg), 5-(4, 4, 5, 5- Tetramethyl-[l, 3, 2]dioxaborolan-2-yl)-7-(toluene-4-sulfonyl)-7H-pyrrolo[2, 3-d]pyrimidine (compound 1005), PdCl2dppf2 (7 mg), and potassium phosphate (32 mg) were heated in 1, 4- dioxane (2 mL) at 80 0C overnight. To the reaction was added aqueous lithium hydroxide solution (2 mL). After heating at 600C for Ih, water (20 mL) was added. Extraction with dichloromethane (3X), drying, evaporation and purification (SiO2, 50-100% ethyl acetate/hexane) gave 3.7 mg of 2-[6-phenyl-2-(7eta-pyrrolo[2, 3-d]pyrimidin-5-yl)-pyrimidin- 4-ylamino]-N-(2, 2, 2-trifluoro-ethyl)-propionamide (compound 18).In the synthesis of intermediate 2, Using 2, 4, 6-trichloropyrimidine instead of Intermediate 1, The synthesis was carried out in the same manner. Under an argon gas flow, Intermediate 1 (11.9 g, 50 mmol) was added successively to the reaction vessel, Phenylboronic acid (7.9 g, 65 mmol), Tetrakis (triphenylphosphine) palladium (1.73 g, 1.5 mmol), Toluene 170 mL, Ethanol 30 mL, 2M aqueous sodium carbonate solution (50 mL), And the mixture was heated under reflux for 8 hours.After the reaction solution was cooled to room temperature, The organic layer was separated, The organic solvent was removed by distillation under reduced pressure.The resulting residue was purified by silica gel chromatography, To give intermediate 2 (11.6 g, 49 mmol (yield 98%)).A mixture of compound, The following compounds presented in Examples 40-47 were prepared in accordance with Scheme 5, by a procedure analogous to that disclosed in Example 39, using starting materials with the appropriate substitution. (1.0 eq), pyridinylphenylboronic acid (1.05 eq, CAS No. 170230-28-1), Pd(PPh3)4 (0.012 eq), Na2CO3 (2.0 eq, 3 M) in THF (0.3 M) was heated at 60 C. for 16 h. After completion of the reaction, the volatiles were removed under vacuum, and the resulting solution was extracted with CH2Cl2. The combined organic extract was washed with brine solution, dried over Na2SO4. Then the resulting solution was concentrated under reduced pressure and purified by column chromatography to obtain Reactant B8 in a yield of 68%. The purified product was identified as Reactant B8 by FD-MS analysis. FD-MS analysis C21H14ClN3: theoretical value of 343.81 and observed value of 343.81.<1-i> was synthesized by the following Scheme 9. In a 5000 mL round bottom flask, 100.6 g (0.506 mol) <1-f> from Scheme 6, 125.15 g (0.556 mol) <1-h> from Scheme 8, 209.60 g (1.517 mol) of potassium carbonate (K2CO3), 11.69 g (0.010 mmol) of tetrakistriphenylphosphinepalladium (Pd (PPh3) 4), 500 mL of water, 1000 mL of toluene and 500 mL of ethanol were added and refluxed for 12 hours. After the reaction was completed, the resulting product was separated into layers to remove the aqueous layer, and the organic layer was separated and concentrated under reduced pressure. Then, the precipitate was precipitated using methanol and filtered. 100 g (yield 57.5%) <1-i> was obtained.Under nitrogen, Compound A was dissolved in tetrahydrofuran / toluene (5: 1) and 1.2 equivalents of Compound B was added. 4.4 equivalents of potassium carbonate was dissolved in distilled water (DI water) and 0.05 equivalent of Pd (0) was added.
