실험 절차

1.3 g (3.6 mmol) of 7-chloro-3-(5-chloromethyl-1,2,4-oxadiazol-3-yl)-5-methyl-5,6-dihydro-4H-imidazo[1,5-a][1,4]benzodiazepin-6-one were stirred at room temperature overnight with 1.6 ml (8.9 mmol) of diisobutylamine and 15 ml of N,N-dimethylformamide. By evaporation of the reaction mixture and chromatography of the residue on silica gel while eluting with ethyl acetate there was obtained 0.69 g (42%) of 7-chloro-3-(5-diisobutylaminomethyl-1,2,4-oxadiazol-3-yl)-5-methyl-5,6-dihydro-4H-imidazo[1,5-a][1,4]benzodiazepin-6-one of m.p. 158°-160°, which was converted into the hydrochloride of m.p. 125°-128°.
