実験手順

A suspension of 1.0 g (0.00275 mol) of 3-(4-chloromethyl-thiazol-2-yl)-8-fluoro-5-methyl-5,6-dihydro-4H-imidazo[1,5-a][1,4]benzodiazepin-6-one in 50 ml of tetrahydrofuran was treated wth 4.1 ml (0.033 mol) of diallylamine. After stirring at reflux for 18 hrs. the solution obtained was completely freed from the solvents. The residue was chromatographed over silica gel with dichloromethane/methanol 19:1 as the eluent and recrystallized from hot isopropyl ether. There was obtained 0.76 g (66%) of 3-(4-diallylaminomethyl-thiazol-2-yl)-8-fluoro-5-methyl-5,6-dihydro-4H-imidazo[1,5-a][1,4]benzodiazepin-6-one as white crystals; m.p. 125-127°.
