Reaction Steps

0.075 g (0.00019 mol) of 3-(4-dipropylaminomethyl-oxazol-2-yl)-5-methyl-5,6-dihydro-4H-imidazo[1,5-a]thieno-[2,3-f][1,4]diazepin-6-one was dissolved in 50 ml of ethanol and treated with 0.05 ml (0.00019 mol) of 3.7N ethanolic hydrochloric acid. The solution was completely freed from the solvents and recrystallized from ethanol/diethyl ether. There was obtained 0.07 g (86%) of 3-(4-dipropylaminomethyl-oxazol-2-yl)-5-methyl-5,6-dihydro-4H-imidazo[1,5-a]thieno[2,3-f][1,4]-diazepin-6-one hydrochloride as whitish yellow crystals; m.p. 210°-215°.
