Participants

Reaction Steps

730 mg (31.8 mmol) of sodium were dissolved in 40 ml of methanol. 2.37 g (34.1 mmol) of hydroxylamine hydrochloride and 7.1 g (22.3 mmol) of (S)-8-trifluoromethyl-12,12a-dihydro-9-oxo-9H,11H-azeto[2,1-c]imidazo[1,5-a][1,4]benzodiazepine-1-carbonitrile were added in succession at room temperature and the mixture was stirred at room temperature overnight. By evaporating the solvent there were obtained 7.8 g (100%) of (S)-8-trifluoromethyl-12,12a-dihydro-9-oxo-9H,11H-azeto[2,1-c]imidazo[1,5-a][1,4]benzodiazepine-1-carboxamidoxime, which was used in the next step without further purification.
