実験手順

A mixture of 9-(1-benzyl-4-methyl-1H-imidazol-2-yl)-8-phenyl-8,9-dihydro-2H-pyrido[4,3,2-de]phthalazin-3(7H)-one (40 mg, 0.09 mmol) and palladium hydroxide on carbon catalyst (40 mg, 20% wt) in anhydrous methanol (15 mL) was purged with hydrogen (1 bar) at room temperature for 12 hr. The mixture was filtered and the filtrate was concentrated to give crude product, which was purified by pre-HPLC to give 9-(4-methyl-1H-imidazol-2-yl)-8-phenyl-8,9-dihydro-2H-pyrido[4,3,2-de]phthalazin-3(7H)-one (27 mg, yield 87%). 1H-NMR (400 MHz, CD3OD) δ (ppm): 2.22 (dd, 3H), 4.77-4.86 (m, 2H), 7.06 (s, 1H), 7.20 (d, 1H), 7.36 (t, 5H), 7.55 (d, 1H), 7.62 (t, 1H); LC-MS (ESI) m/z: 3-(4 (M+1)+.
