Reaction Steps

0.10 g (0.00023 mol) of 7-chloro-3-(4-diisopropylaminomethyl-oxazol-2-yl)-5-methyl-5,6-dihydro-4H-imidazo[1,5-a][1,4]benzodiazepin-6-one was dissolved in 10 ml of ethanol and treated with 0.063 ml (0.00023 mol) of 3.7N ethanolic hydrochloric acid. The solution was completely freed from the solvents and recrystallized from ethanol/diethyl ether. There was obtained 0.10 g (92%) of 7-chloro-3-(4-diisopropylamino-methyl-oxazol-2-yl)-5-methyl-5,6-dihydro-4H-imidazo[1,5-a][1,4]benzodiazepin-6-one hydrochloride as white crystals; m.p. 228°-230°.
