実験手順

3.0 g (8.1 mmol) of (S)-1-(5-aminomethyl-1,2,4-oxadiazol-3-yl)-8-chloro-11,12,13,13a-tetrahydro-9H-imidazo[1,5-a]pyrrolo[2,1-c][1,4]benzodiazepin-9-one, 20 ml of N,N-dimethylformamide, 3 ml (20 mmol) of 1,8-diazabicyclo[5.4.0]undec-7-ene (1.5-5) and 6.54 g (54 mmol) of allyl bromide were stirred at 40° overnight. The reaction mixture was concentrated, the residue was dissolved in methylene chloride and the solution was washed with water. After drying the product was purified by chromatography on silica gel while eluting with melthylene chloride/methanol 19/1. There were obtained 1.8 g (49%) of (S)-1-(5-diallylaminomethyl-1,2,4-oxadiazol-3-yl)-8-chloro-11,12,13,13a-tetrahydro-9H-imidazo[1,5-a]pyrrolo[2,1-c][1,4]-benzodiazepin-9-one, which was converted into the hydrochloride.
