Procedure

To a solution of imidazo[1,2-a]pyrazine-6-carbonitrile (5-1) (180 mg, 1.25 mmol) in methanol (15 mL) were added Raney nickel (slurry in water, 150 mg) and 1 N ammonia. The reaction mixture was stirred under H2 (1 atm) for 2 h. The mixture was filtered, and the filtrate was concentrated to afford the title compound (160 mg). MS (m/z): 149.1 (M+H)+
