Procedure

3,8-Dihydrocyclopent[a]inden-1[2H]-one (7.6 g.) in ethanol (400 ml) was hydrogenated at atmospheric pressure and room temperature in the presence of 10% palladium on charcoal (0.9 g) until one molar equivalent of hydrogen had been absorbed. The catalyst was filtered off and the filtrate evaporated to dryness to give a brown gum which was distilled at 90° /0.1 torr to produce a colourless oil.
