실험 절차

Following the procedures of example 14, (S)-benzyl-2-(2-bromoacetyl)pyrrolidine-1-carboxylate (0.400 g, 1.23 mmol) and 2-amino-3-bromo-4-methylpyridine (0.2344 g, 1.25 mmol), produced the crude material which was adsorbed onto silica gel and purified by flash chromatography (12 g SiO2, 0-50% ethyl acetate in hexanes) to give (S)-benzyl-2-(8-bromo-7-methylimidazo[1,2-a]pyridin-2-yl)pyrrolidine-1-carboxylate (0.239 g, 0.58 mmol, 47%).

후처리

  1. customproduced the crude material which
  2. custompurified by flash chromatography (12 g SiO2, 0-50% ethyl acetate in hexanes)
