4-Chloro-1-(4-methoxyphenyl)-1-butanone (5 g, 23.5 mmol) was dissolved in tetrahydrofuran (50 ml). 10% Palladium carbon (water-containing product, 500 mg) was added and the mixture was subjected to catalytic reduction under hydrogen pressure (0.8 MPa, 50° C. for 3 h). The catalyst was filtered off and the filtrate was concentrated under reduced pressure to give 1-(4-chlorobutyl)-4-methoxybenzene (4.6 g, yield 99%).
