The catalyst was filtered off and the filtrate was evaporated to give ethyl 4-(1-phenylcyclohexyl)butanoate as an oil. 1H NMR (400 MHz, CCl3D) δ ppm 7.31 (2H, s), 7.30 (2H, s), 7.13-7.20 (1H, m), 4.06 (2H, q, J=7.03 Hz), 2.04-2.13 (4H, m), 1.33-1.63 (10H, m), 1.24-1.32 (2H, m), 1.20 (3H, t, J=7.14 Hz).
