A solution of 1-(4-benzyloxyphenyl) propan-2-one ethylene ketal (6 g) in ethanol (100 ml) was hydrogenated at 45 psi and ambient temperature in the presence of 10% Pd/C until hydrogen uptake had ceased. The solution was filtered and evaporated to give a light coloured oil which crystallised on standing m.p. 61°-64°.
