A solution of 6 (0.85 g, 2.6 mmol) in 50 mL MeOH was mixed with 85 mg of Pd/C and hydrogenated with H2 at a pressure of 10 psi for 3 hours. The mixture was then filtered, and the solvent was removed to give 0.76 g (98%) of the title compound as a white solid. 1H NMR (CDCl3): δ 4.44 (s, 3H), 4.69-4.90 (m, 4H), 5.69 (broad s, 2H), 7.44 (d, J=7.8 Hz, 2H), 7.81-8.05 (m, 4H), 8.14 (d, J=1.6, 6.9 Hz, 1H); HRMS: Calcd. for C17H17N3O2 295.1321, found 295.1325.
