Hydrogenation of 1-(7-chloro-2H-chromen-4-yl)methanamine hydrochloride (500 mg, 2.6 mmol) was carried out in the presence of Raney Nickel (300 mg) in 2:1 MeOH/HOAc under 50 psi of H2 for 16 h at 30° C. The reaction was filtered through Celite and concentrated in vacuo. Precipitation from EtOAc and filtration gave 280 mg (56%) of the title compound as a white solid. [M+H] calc'd for C10H12ClNO, 198. found 198.
