実験手順

7.74 g (17 mmol) of crude (S)-7-fluoro-12,12a-dihydro-1-[5-(N-BOC-N-methylaminomethyl)-1,2,4-oxadiazol-3-yl]-9H,11H-azeto[2,1-c]imidazo[1,5-a][1,4]benzodiazepin-9-one were stirred for 2 hours in 25 ml of trifluoroacetic acid. The solution was concentrated, the residue was taken up in water and the solution was washed twice with methylene chloride. The aqueous phase was made alkaline with 25% ammonia and extracted seven times with methylene chloride. There were obtained 5.12 g (85%) of (S)-7-fluoro-12,12a-dihydro-1-(5-methylaminomethyl-1,2,4-oxadiazol-3-yl)-9H,11H-azeto[2,1-c]imidazo-[1,5-a][1,4]benzodiazepin-9-one of m.p. 187°-190°, which was converted into the hydrochloride of m.p. 155°-160°.
