実験手順
30.0 g of (Z)-4-butyryloxy-5-isobutylidene-3-pyrrolin-2-one (produced according to Example 3) was dissolved in 300 ml of toluene, mixed with 3.0 g of palladium/activated carbon(5 percent of pf Pd) and hydrogenated for 24 hours in an autoclave at 2 MPa (20 bar). Then the catalyst was filtered off, the filtrate was concentrated by evaporation and the residue was recrystallized from hexane. The yield of the title compound was 23.50 g (77 percent of theory). The title compound had a melting point of 101.5° to 102.7° C. Other data concerning the title compound was:
