8-(4-(Dimethoxymethyl)phenyl)-9-phenyl-8,9-dihydro-2H-pyrido[4,3,2-de]phthalazin-3(7H)-one (89 mg, 0.22 mmol) and 20 ml of 3 N hydrochloric acid were added and the mixture was stirred at room temperature for 2 h. The resulting mixture was neutralized with potassium carbonate and then filtered to give 4-(3-oxo-9-phenyl-3,7,8,9-tetrahydro-2H-pyrido[4,3,2-de]phthalazin-8-yl)benzaldehyde (59, yield 73%). LC-MS (ESI) m/z: 368.
