Participants

Reaction Steps

A mixture of 8,9-bis(4-(diethoxymethyl)phenyl)-8,9-dihydro-2H-pyrido[4,3,2-de]phthalazin-3(7H)-one (120 mg, 0.22 mmol) in 3N hydrochloric acid (5 mL) was stirred at room temperature for 3 hr. Then the mixture was neutralized (basified) with potassium carbonate to pH=8. The resulting suspension was filtered to give 4,4′-(3-oxo-3,7,8,9-tetrahydro-2H-pyrido[4,3,2-de]phthalazine-8,9-diyl)dibenzaldehyde (80 mg, yield 97%) as a light yellow solid. LC-MS (ESI) m/z: 396 (M+1)+.
