반응 단계

A solution of 4.14 g (14.5 mmol) of sodium carbonate decahydrate in 20 ml of water is added dropwise to a mixture of 3.0 g (11.6 mmol) of 8-fluoro-5,6-dihydro-5-methyl-6-oxo-4H-imidazo[1,5-a][1,4]benzodiazepine-3-carboxaldehyde, 0.99 g (14.5 mmol) of hydroxylamine hydrochloride and 60 ml of water, the mixture is stirred at 70° C. for 1 hour, cooled in an ice-bath and the separated material is filtered off under suction and washed with water. The still moist substance is recrystallised from ethanol and yields 8-fluoro-5,6-dihydro-5-methyl-6-oxo-4H-imidazo[1,5-a][1,4]benzodiazepine-3-carboxaldehyde-3-oxime of melting point 247°-250° C.
