2-(4-BROMO-1H-PYRAZOL-1-YL)PYRIMIDINE Use and Manufacturing

To a solution of General procedure: The ligand pzpm (47.4mg, 0.32mmol) was dissolved in CH2Cl2 (10ml), and added to a suspension of [NiBr2(DME)] (100mg, 0.32mmol) in CH2Cl2 (20ml), in a Schlenk tube, under nitrogen. The reaction was stirred for 18h at room temperature. The resulting suspension was filtered and the solid product was washed twice with hexane (2×10ml) and dried in vacuum, yielding 94mg (82%) of a mustard yellow powder.To a solution of propane- 1 -sulfonic acid {3-[ l-(2, 6-dichloro-benzoyl)-5-(4, 4, 5, 5-tetramethyl- [l , 3, 2]dioxaborolan-2-yl)- 1 H-pyrrolo[2, 3-b]pyridine-3-carbonyl]-2, 4-difluoro-phenyl}-amide (32, 18 mg, 0.026 mmol) and 2-(4-bromo-pyrazol-l -yl)-pyrimidine (33, 4.95 mg, 0.022 mmol) in 800 muL· of acetonitrile is added 400 mu of 1 aqueous potassium carbonate and approximately 1-2 mg of [Iota , Gamma- bis(diphenylphosphino)ferrocene] dichloro-palladium (II) (PdCI2 dppf). The reaction mixture is microwave irradiated at 145 C for 15 minutes, then neutralized with acetic acid, and extracted with 2 x 1 mL of ethyl acetate. The combined organic layer is concentrated under vacuum, the residue dissolved in 500 x of dimethylsulfoxide and purified by HPLC using a CI 8 column, eluting with water/acetonitrile and 0.1 % trifluoroacetic acid, 20-100% acetonitrile at 6 mL per minute. Appropriate fractions are combined and concentrated under vacuum to provide the desired compound. MS (ESI) [M+H+]+ = 524.5.To a solution of 2-pyrazol-1-yl-pyrimidine (0.55 g, 3.7 mmol) in acetic acid (5 ml_) was added bromine (1.2 g, 7.5 mmol) in acetic acid (3 ml_) dropwisely. After addition, the reaction mixture was stirred at room temperature overnight. After removed the acetic acid, the crude product was purified using column chromatography (2% methanol in dichloromethane) to give 0.7 g of pure product in 85 % yield.
