Reference of 59907-13-0, These common heterocyclic compound, 59907-13-0, name is 2-Bromo-1-fluoro-3-methylbenzene, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
General procedure: Method A ( Buchwald-Hartwia ) To a mixture of C-1 (1 eq), BB-8 (1.3 eq) and sodium tert-butoxide (2 eq) in toluene (3 to 10 mL/mmol) under N2, was added BINAP (0.2 eq) and Pd2(dba)3 (0.1 eq). The rxn mixture was flushed with N2, heated at a given temperature and stirred for a given time (see Table 25). It was partitioned between water and EtOAc and the org. phase was washed with brine, dried over MgSC>4 and concentrated in vacuo. The crude was purified by CC using Hept/EtOAc. When necessary an additional purification by prep. LC-MS was performed.
Statistics shows that 2-Bromo-1-fluoro-3-methylbenzene is playing an increasingly important role. we look forward to future research findings about 59907-13-0.
