Synthetic Route of 717843-51-1 ,Some common heterocyclic compound, 717843-51-1, molecular formula is C7H8BrNO, 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: To a mixture of the appropriate amine E (1 eq), the appropriate halide (1.05 to 1.2 eq) and sodium ferf-butoxide (2 eq) in toluene (3 mL/mmol) under N , was added BINAP (0.2 eq) and Pd2(dba)3 (0.1 eq). The rxn mixture was flushed with N , heated to a given temperature in a sealed vial and stirred for a given time (see Table 27). It was partitioned between water and EtOAc and the org. phase was washed with brine, dried over MgSCh and concentrated in vacuo. The crude was purified by CC using Hept/EtOAc.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles. 717843-51-1, 3-Bromo-2-methoxy-4-methylpyridine, other downstream synthetic routes, hurry up and to see.
