실험 절차

A mixture of methyl 3-(4-(4-(cyclopropanecarbonyl)piperazine-1-carbonyl)phenyl)-4-oxo-2-phenyl-1,2,3,4-tetrahydroquinoline-5-carboxylate (90 mg, 0.16 mmol) in 85% hydrazine monohydrate (5 mL) and methanol (2 mL) was stirred at 25° C. for 4 hr. The mixture was extracted with ethyl acetate (50 mL×3). The combined organic layers were washed with brine, dried over anhydrous sodium sulfate, and concentrated to give crude product. The crude product was purified by prep-HPLC to give 9-(4-(4-(cyclopropanecarbonyl)piperazine-1-carbonyl)phenyl)-8-phenyl-8,9-dihydro-2H-pyrido[4,3,2-de]phthalazin-3(7H)-one (18 mg, yield 22%) as a white solid. 1H-NMR (400 MHz, CD3OD) δ (ppm): 0.86-0.94 (m, 4H), 2.00 (s, 1H), 3.33-3.82 (m, 8H), 4.41-4.43 (d, J=8.4 Hz, 1H), 4.78-4.80 (d, J=8.4 Hz, 1H), 7.21-7.27 (m, 6H), 7.30-7.35 (m, 4H), 7.58-7.60 (m, 1H), 7.65-7.69 (t, J=8.0 Hz, 4H); LC-MS (ESI) m/z: 520(M+1)+.
