Reaction Steps

A solution of 2-(4-chloro-2-oxo-1,2-dihydropyridin-3-yl)-6-(2-pyrrolidin-1-ylethyl)-6,7-dihydroimidazo[4,5-f]isoindol-5(3H)-one (50 mg, 0.126 mmol), (1S)-2-(5-chloro-2-methylphenyl)-1-methylethylamine (30 mg, 0.164 mmol) and DIEA (66 uL, 0.38 mmol) in 2 mL of EtOH was heated at 80° C. for 24 h. Then the solvent was evaporated and the residue was purified by column (silica gel, DCM:MeOH 95:5) to give 2-(4-((1S)-2-(5-cloro-2-methylphenyl)-1-methylethylamino)-2-oxo-1,2-dihydropyridin-3-yl)-6-(2-pyrrolidin-1-ylethyl)-6,7-dihydroimidazo[4,5-f]isoindol-5(3H)-one (41 mg, 59%) as yellow solid. ESI-MS: m/z (MH+) 545.5. 1H NMR (300 MHz, CDCl3): δ 7.96 (d, J=44.8 Hz, 1H), 7.51 (d, J=66.3 Hz, 1H), 7.20 (m, 2H), 7.03 (m, 2H), 5.86 (m, 1H), 4.59 (m, 2H), 3.93 (m, 3H), 2.96-3.13 (m, 8H), 2.32 (s, 3H), 1.91 (m, 4H), 1.38 (d, J=7.35 Hz, 3H).
