実験手順

A solution of 0.81 g (0.002 mol) of (S)-8-chloro-1-(4-chloromethyl-thiazol-2-yl)-11,12,13,13a-tetrahydro-9H-imidazo[1,5-a]pyrrolo[2,1-c][1,4]benzodiazepin-9-one in 5 ml of tetrahydrofuran was treated with 3 ml (0.024 mol) of diallylamine and stirred at 50° for 8 hrs. All volatiles were removed in a water-jet vacuum and the residue was chromatographed over silica gel with methylene chloride/methanol 98:2 as the eluent. After recrystallization from diethyl ether there was obtained 0.52 g (55%) of (S)-8-chloro-1-(4-diallylaminomethyl-thiazol-2-yl)-11,12,13,13a-tetrahydro-9H-imidazo[1,5-a]pyrrolo[2,1-c][1,4]benzodiazepin-9-one in the form of white crystals; m.p. 186°-187° and [α]D20 =-67.5° (MeOH, c=1%).
