Related Products of 69214-33-1, These common heterocyclic compound, 69214-33-1, name is 8-Chloroimidazo[1,2-a]pyrazine, 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.
N-Bromosuccinimide (2.0 g, 11.6 mmol) was added to a stirred solution of intermediate 3 (1.78 g, 11.58 mmol) in DCM (50 ml). The mixture was stirred at RT for 2 h. and then diluted with further DCM and washed with a saturated solution of sodium carbonate. The organic layer was separated, dried (Na2S04), filtered and the solvent evaporated in vacuo to yield a 72/28 mixture of 3-bromo-8-chloro-imidazo[l,2-a]- pyrazine and 3,8-dibromo-imidazo[l,2-a]pyrazine (intermediate 15) (5.89 g, 99%) as white solid.
Statistics shows that 8-Chloroimidazo[1,2-a]pyrazine is playing an increasingly important role. we look forward to future research findings about 69214-33-1.
