Procedure

1-(4-Carbomethoxyphenyl)propan-2-one oxime (10.0 g) in absolute alcohol (200 ml) and chloroform (25 ml) was hydrogenated on a Parr hydrogenator at 50 psi and at 50° in the presence of platinum oxide (250 mg) until hydrogen uptake had ceased. The catalyst was removed and the residue was recrystallised as the hydrochloride from methanol/ethyl acetate, mp 206°-210° (8.5 g). γ (d6DMSO) 8.84 (3H, d, 6 Hz), 6.2-7.5 (3H, m), 6.17 (3H, s), 2.59 (2H, d, J=8 Hz), 2.09 (2H, d, J=8 Hz), 1.50 (2H, br).
