Procedure

Ethyl 2-(4-(diethoxymethyl)phenyl)-3-(4-(dimethylcarbamoyl)phenyl)-4-oxo-1,2,3,4-tetrahydroquinoline-5-carboxylate (250 mg, 0.46 mmol) and hydrazine monohydrate (85%, 5 mL) were added in MeOH (15 mL) and the mixture was stirred room temperature for 5 h. The resulting mixture was concentrated under reduced pressure to a volume of 15 mL and then filtered; the filtrate was evaporated to give the title compound as a white solid (180 mg, yield 76%). LC-MS (ESI) m/z: 513(M+1)+.
