Versuchsvorschrift
0.37 g (1.04 mmol) 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 in 6 ml ethanol was treated with 0.31 ml (1.14 mmol) of 3.70N ethanolic hydrochloric acid. Crystals separated after adding 20 ml of acetic acid at 0°. There was obtained 0.30 g (73%) 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 hydrochloride (1:1) as whitish crystals; m.p. 250°-252° (dec.).
