2-Chloro-6-fluorobromobenzene Use and Manufacturing
(2) Take (100mmol) M1(100mmol) 2-bromo-3-chlorofluorobenzene, (1%) Pd (PPh3) 4, 40g (300mmol) sodium carbonate, Toluene (800mL), ethanol (200mL) and water (200mL), Heated to reflux, reacted for 8h, the reaction was completed;The reaction solution was extracted with ethyl acetate, and the organic phase was concentrated.Obtained yellow solid M2;General procedure: To a mixture of intermediate C-3 (1 eq), halo-(hetero)arene BB-16 (1.1 to 2 eq) and sodium ferf-butoxide (2 to 2.3 eq) in toluene (3 to 7.8 mL/mmol) under N2, was added BINAP (0.2 to 0.3 eq) and Pd2(dba)3 (0.1 to 0.15 eq). The rxn mixture was flushed with N2, heated under stirring at a given temperature for a given time (see Table ). It was partitioned between water and EtOAc or DCM and the org. phase was washed with brine, dried over MgS04 and concentrated in vacuo. The crude was purified by CC using Hept/EtOAc or DCM/MeOH. When necessary, an additional purification by prep. LC-MS using methods 1, 3, 4, 5, 6 or 10 was performed.Take
