Reaction Steps

0.11 g (0.00026 mol) of 7-chloro-3-(4-dipropylaminomethyl-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 0.07 ml (0.00026 mol) of 3.7N ethanolic hydrochloric acid. The solution was completely freed from the solvents and recrystallized from ethanol/diethyl ether. There was obtained 0.11 g (91%) of 7-chloro-3-(4-dipropylaminomethyl-oxazol-2-yl)-5-methyl-5,6-dihydro-4H-imidazo[1,5-a][1,4]benzodiazepin-6-one hydrochloride as white crystals; m.p. 218°-220°.
