実験手順
Methyl-2H-thiochromene-8-carboxylate (1.83 g, 8.88 mmol) was dissolved in ethanol (100 ml) and treated with 10% PdC (1.5 g). The mixture was then hydrogenated at atmospheric pressure at room temperature. After 19 h the reaction mixture was filtered through celite and evaporated under reduced pressure to give a colourless oil which was dried in vacuo to give the title compound (1.25 g, 68%)
