Reaction Steps

A mixture of methyl 2,3-bis(3-(diethoxymethyl)phenyl)-4-oxo-1,2,3,4-tetrahydroquinoline-5-carboxylate and ethyl 2,3-bis(3-(diethoxymethyl)phenyl)-4-oxo-1,2,3,4-tetrahydroquinoline-5-carboxylate (370 mg, 0.59 mmol) in hydrazine monohydrate (5 mL) and methanol (5 mL) was stirred at 40° C. for 2 hr. The mixture was cooled to room temperature and filtered to give 8,9-bis(3-(diethoxymethyl)phenyl)-8,9-dihydro-2H-pyrido[4,3,2-de]phthalazin-3(7H)-one (250 mg, yield 77%) as a light yellow solid. LC-MS (ESI) m/z: 544(M+1)+.
