실험 절차
A solution of 1.5 g of 3-methyl-1-(4-nitrophenyl)-3-azabicyclo[3.1.0]hexane-2,4-dione in 50 ml of ethanol is hydrogenated in the presence of 0.1 g of 5% palladium on carbon. When the hydrogenation is complete, the catalyst is removed and the filtrate is concentrated and the residue is recrystallised from ethyl acetate/petroleum ether. The title compound is obtained in the form of pale pink crystals with m.p. 137°-139° C. and Rf=0.47 on thin-layer silica gel plates in the system methylene chloride/methanol (15:1).
