Reaction Steps
To a solution of 1-(6-fluoro-2H-chromen-4-yl)methanamine hydrochloride (1.36 g, 7.6 mmol) in MeOH (20 mL) and AcOH (10 mL) was added Raney Nickel (760 mg) at room temperature. The suspension was stirred at rt overnight under 50 psi of H2. The reaction mixture was filtered and concentrated. The residue was dissolved in DCM and washed with sat. NaHCO3, dried (Na2SO4), and concentrated to give 490 mg (36%) of the title compound as a green oil. [M+H] calc'd for C10H12FNO, 182. found 182.
