To the solution of intermediate 10 (900 mg, 2.8 mmol) in EtOH (25 mL) was added 10% Pd/C (400 mg) under an atmosphere of H2 overnight. The reaction was filtered to remove the Pd/C and the filtrate was concentrated and washed with Et2O to give 7-(4-hydroxybutoxy)-3,4-dihydro-1,8-naphthyridin-2(1H)-one (intermediate 11) (360 mg, 55%) as a white solid.
