Procedure

Dissolve 2-azido-1-(2-methoxy-phenyl)-ethanone (3.54 g, 18.5 mmol) in 1328 ml of MeOH and 9 ml of concentrated HCl. Add 943 mg of 10% Pd/C and expose the reaction mixture to 60 psi of H2 for 5 hours at ambient temperature. Filter the catalyst off through a pad of celite and concentrate the filtrate in vacuo to afford 3.74 g of crude 2-amino-1-(2-methoxyphenyl)-ethanone as the hydrochloride salt.
