実験手順

A solution of 1.1 g (0.00281 mol) of (S)-8-chloro-1-(4-chloromethyl-thiazol-2-yl)-12,12a-dihydro-9H,11H-azeto[2,1-c]imidazo[1,5-a][1,4]benzodiazepin-9-one in 70 ml of tetrahydrofuran was treated with 7.7 ml (0.0562 mol) of dipropylamine. After stirring at reflux for 16 hrs. the solution obtained was completely freed from the solvents. The residue was chromatographed over silica gel with ethyl acetate as the eluent and recrystallized from ethyl acetate/ether. There was obtained 0.82 g (64%) 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 as white crystals; m.p. 200°-201° and [α]D20 =-181.2° (CHCl3, c=1%).
