HCID 6228DimethylformamideSolvent

Procedure

1.8 g (5 mmol) of (S) 1-(5-chloromethyl-1,2,4-oxadiazol-3-yl)-7-fluoro-12,12a-dihydro-9H,11H-azeto[2,1-c]imidazo[1,5-a][1,4]benzodiazepin-9-one were stirred at room temperature overnight with mmol) of dipropylamine and 20 ml of N,N-dimethylformamide. By evaporation of the solvent and chromatography of the residue on silica gel while eluting with ethyl acetate there were obtained 1.8 g (85%) of (S)-1-(5-dipropylaminomethyl-1,2,4-oxadiazol-3-yl)-7-fluoro-12,12a-dihydro-9H,11H-azeto[2,1-c]imidazo[1,5-a][1,4]benzodiazepin-9-one, which was converted into the hydrochloride (amorphous).
