N-[2-(4-methoxy-3-nitrophenyl)ethyl]acetamide (7.4 g) in 150 mL of ethanol was hydrogenated in the presence of 3.5 mL of concentrated HCl and 0.4 g of 10% Pd/C at 30-40 psi for 3 hours in a Parr shaker. After this time, the catalyst was filtered off, and the solvent was removed by rotary evaporation to yield 7.1 g of N-[-2-(3-amino-4-methoxyphenyl)ethyl]acetamide hydrochloride as an off-white solid (94.0% yield). 1HNMR (DMSO-d6) spectrum was consistent with the desired product.
