実験手順

A solution of 6-methoxy-4-benzopyranone (31.6 g), triethylamine (4.9 ml) and 10% palladium on carbon (3.16 g) in absolute ethanol (1.7 l) is stirred under an atmosphere of hydrogen for 19 hours. The reaction mixture is filtered and evaporated in vacuo yielding the desired hydrogenated product as a pale yellow liquid.
