Reaction Steps

A mixture of 4-(9-(4-fluorophenyl)-3-oxo-3,7,8,9-tetrahydro-2H-pyrido[4,3,2-de]phthalazin-8-yl)benzaldehyde (150 mg, 0.39 mmol), tert-butyl piperazine-1-carboxylate (218 mg, 1.17 mmol), and acetic acid (117 mg, 1.95 mmol) in dichloromethane (20 mL) was stirred at room temperature overnight. Then the mixture was cooled to 0° C. and sodium triacetoxyborohydride (124 mg, 0.58 mmol) was added. After the addition, the mixture was stirred at room temperature for 5 h. Dichloromethane was removed under reduced pressure. The crude product was purified by flash chromatography to give the title compound (70 mg, yield 32%). LC-MS (ESI) m/z: 556 (M+1)+.
