実験手順

0.91 g (0.0020 mol) of (S)-8-chloro-1-(4-dipropylaminomethyl-thiazol-2-yl)-12,12a-dihydro-9H,11H-azeto[2,1-c]imidazo[1,5-a][1,4]benzodiazepin-9-one in 30 ml of dichloromethane was treated with 0.54 ml (0.0020 mol) of 3.7N ethanolic hydrochloric acid. After stirring at room temperature for 10 minutes the solution was completely freed from the solvents. The residue was recrystallized from ethanol/ether. There was obtained 0.85 g (87%) of (S)-8-chloro-1-(4-dipropylaminomethyl-thiazol-2-yl)-12,12a-dihydro-9H,11H-azeto[2,1-c]imidazo[1,5-a][1,4]benzodiazepin-9-one hydrochloride (1:1) as white crystals; m.p. 221-223° and [α]D20 =-245.7° (MeOH, c=1%).
