실험 절차

In 200 ml of tetrahydrofuran was dissolved 10.8 g of 5-phenyl-2-[3-(3,4-methylenedioxyphenyl)-propenoyl]-cyclohexane-1,3-dione prepared in step (1) above, and 2 g of a 5% palladium-carbon catalyst was added to the solution and catalytic reduction was carried out for 7 hours with hydrogen under atmospheric pressure. The catalyst was removed by filtration and tetrahydrofuran was removed by distillation. Recrystallization from isopropyl alcohol have 7.5 g (the yield being 70%) of the desired 5-phenyl-2-[3-(3,4-methylenedioxyphenyl)-propionyl]-cyclohexane-1,3-dione.
