실험 절차

A mixture of 4,4′-(3-oxo-3,7,8,9-tetrahydro-2H-pyrido[4,3,2-de]phthalazine-8,9-diyl)dibenzaldehyde (80 mg, 0.21 mmol) and 27% methylamine alcohol solution (94 mg, 0.82 mmol) in methanol (10 mL) was stirred at room temperature for 40 min. The mixture was then cooled to 0° C. Sodium borohydride (24 mg, 0.64 mmol) was added. After the addition, the mixture was stirred at room temperature for 4 hr. Methanol was removed under reduced pressure. The residue was washed with ethyl acetate and filtered. The filtrate was concentrated to give 8,9-bis(4-((methylamino)methyl)phenyl-8,9-dihydro-2H-pyrido[4,3,2-de]phthalazin-3(7H)-one (29.5 mg, yield 33%) as a light yellow solid. 1H-NMR (400 MHz, DMSO-d6) δ 2.20 (d, J=8.8 Hz, 6H), 3.52-3.53 (d, J=2.4 Hz, 4H), 4.31-4.33 (d, J=6.4 Hz, 1H), 4.76-4.77 (d, J=6.4 Hz, 1H), 7.06-7.08 (d, J=6.4 Hz, 2H), 7.12-7.17 (m, 5H), 7.35-7.38 (t, J=6.4 Hz, 2H), 7.49-7.57 (t, J=10.0 Hz, 1H); LC-MS (ESI) m/z: 426(M+1)+.
