Reaction Steps

A mixture of 8-(1-benzyl-1H-imidazol-2-yl)-9-(4-fluorophenyl)-8,9-dihydro-2H-pyrido[4,3,2-de]phthalazin-3(7H)-one (200 mg, 0.46 mmol) and palladium hydroxide (200 mg) in methanol (4 mL) was purged with hydrogen and stirred at 60° C. for 18 hr. Then the mixture was filtered, evaporated to remove the solvent, and washed the solid with ethyl acetate to obtain the title compound (150 mg, yield 94%). LC-MS (ESI) m/z: 348 (M+1)+. 1H-NMR (400 MHz, DMSO-d6) δ (ppm): 4.93 (d, J=8.4 Hz, 1H), 5.21 (d, J=8.4 Hz, 1H), 7.10 (t, J=8.4 Hz, 2H), 7.21-7.30 (m, 3H), 7.37 (s, 1H), 7.45-7.49 (m, 3H), 4.58 (d, J=10 Hz, 1H), 7.62-7.67 (m, 1H), 7.87 (s, 1H).
