실험 절차

0.66 g (1.9 mmol) of 3-(5-chloromethyl-1,2,4-oxadiazol-3-yl)-8-fluoro-5-methyl-5,6-dihydro-4H-imidazo[1,5-a][1,4]benzodiazepin-6-one was dissolved in 20 ml of N,N-dimethylformamide. A weak stream of ethylamine gas was introduced at room temperature, the reaction temperature rising to 36°. After stirring at room temperature for 16 hrs. the solution obtained was completely freed from the solvents. The residue was chromatographed over silica gel with methylene chloride/methanol 19:1 as the eluent. After concentration there was obtained a beige foam which was taken up in ether. There was obtained 0.40 g (59%) of 3-(5-ethylaminomethyl-1,2,4-oxadiazol-3-yl)-8-fluoro-5-methyl-5,6-dihydro-4H-imidazo[1,5-a][1,4]benzodiazepin-6-one as beige crystals; m.p. 166°-168°.
