To a solution of ethyl 7-fluoro-3-(1-methyl-1H-1,2,4-triazol-5-yl)-4-oxo-2-phenyl-1,2,3,4-tetrahydroquinoline-5-carboxylate (186 mg, 0.47 mmol) in methanol (1 mL) was added hydrazine monohydrate (0.5 mL), and the mixture was stirred at 25° C. for 15 hr. Then the mixture was filtered to obtain a white solid (40 mg, yield 24%). LC-MS (ESI) m/z: 363 (M+1)+. 1H-NMR (400 MHz, DMSO-d6) δ (ppm): 3.63 (s, 3H), 4.94-5.03 (m, 2H), 6.91-6.94 (dd, J1=11.6 Hz, J2=2.4 Hz, 1H), 7.05-7.08 (dd, J1=9.6 Hz, J2=2.4 Hz, 1H), 7.29-7.35 (m, 3H), 7.42-7.48 (m, 2H), 7.74 (s, 1H), 7.79 (s, 1H), 12.34 (s, 1H).
