Reaction Conditions

Reaction Steps

N-[4-(Hydroxymethyl)-3-methylphenyl]acetamide (D51) (0.36 g, 2 mmol) and manganese dioxide (0.875 g, 10 mmol) were combined in acetonitrile (16 ml) and heated to 120° C. in the microwave for 7 minutes. The MnO2 was filtered off and the reaction mixture was concentrated to give the crude product which was purified by column chromatography. Elution with 0-100% EtOAc/petroleum ether yielded the title compound as a cream solid (0.326 g). δH (CDCl3, 400 MHz) 10.27 (1H, s), 7.79 (1H, d), 7.50 (1H, d), 7.45 (1H, s), 7.35 (1H, br.s), 2.66 (3H, s), 2.20 (3H, s). MH+ 178.2.
