To a pressure vessel, mixture of 0.675 g. of 2-(p-biphenylyl)-2-penten-4-ol (obtainable by Example 1) and 0.5 g. 10% palladium on carbon in 175 ml. of ethanol, is added hydrogen at about 2 at. pressure via low pressure hydrogenation. The catalyst is then removed, and the solution is evaporated to give a colorless oil which solidifies on standing to give solid 2-(p-biphenylyl)-pentan-4-ol, m.p. 53° C., which may also be designated 4-(p-biphenylyl)-pentan-2-ol.
