Participants

Reaction Steps

The mixture of tert-butyl 4-(4-(9-(4-fluorophenyl)-3-oxo-3,7,8,9-tetrahydro-2H-pyrido[4,3,2-de]phthalazin-8-yl)benzyl)piperazine-1-carboxylate (70 mg, 0.12 mmol) in a solution of HCl(g) in acetonitrile (sat. 10 mL) was stirred for 3 hr at room temperature. Then the mixture was filtered to give the crude product. The crude product was purified by flash chromatography to give the title compound as a hydrochloride salt (35 mg, yield 60%). 1H-NMR (400 MHz, CD3OD) δ (ppm): 2.63-2.64 (m, 4H), 3.19-3.21 (m, 4H), 3.54 (s, 2H), 4.29-4.31 (d, J=8.0 Hz, 1H), 4.69-4.71 (d, J=8.4 Hz, 1H), 6.89-6.93 (m, 2H), 7.07-7.10 (m, 2H), 7.19-7.26 (m, 5H), 7.54-7.56 (m, 1H), 7.61-7.65 (m, 1H). LC-MS (ESI) m/z: 456 (M+1)+.
