실험 절차

2,6-Dimethyl-4H-pyran-4-one (5.0 g) in ethanol (40 ml) was hydrogenated under 10% Pd—C (0.5 g) at 10 bar of hydrogen for 2 days. The solution was then evaporated to an oil which was purified by silica-gel MPLC [using a 1:1 mixture of ethyl acetate and hexane as eluant] to give the title product (3.71 g, 74%).
