Reaction Steps

1,8-Naphthyridine (1.0 g, 7.68 mmole) was hydrogenated (50 psi) with 10% Pd/C (100 mg) in absolute ethanol (40 mL) for 18 hr. The mixture was filtered through a pad of Celite® and the filtrate was concentrated to give the title compound (1.04 g) which was sufficiently pure for use in the next step: MS (ES) m/e 135 (M+H)+.
