Procedure

Palladium on carbon (10 wt %, 1.67 g, 1.57 mmol) was added to a solution of 2-azido-1-[4-(methyloxy)phenyl]ethanone (3.0 g, 15.69 mmol) and hydrochloric acid (6.62 mL, 78 mmol) in CH3OH (90 mL) under nitrogen, and the reaction mixture was stirred under hydrogen overnight at 25° C. The mixture was filtered, washed by EtOAc (150 mL), and concentrated to afford an HCl salt of the title compound (3.0 g) as a yellow solid. LC-MS (ES) m/z=166 [M+H]+.
