5.4 g of 1-chloro-4-[trans-4-(5-methoxy-2-pentenyl)cyclohexyl]benzene are dissolved in 80 ml of ethyl acetate in an autoclave, treated with 1 g of Raney nickel and hydrogenated for 7 hours at 60° C. and 5 kg/cm2. The suspension is filtered and evaporated. The residue (5.2 g) is crystallized twice from 30 ml of ethanol each time and gives 3.4 g of 1-chloro-4-[trans-4-(5-methoxypentyl)cyclohexyl]benzene; m.p. (C--I) 52.8° C.
