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-(2-chloro-5-fluorophenyl)-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 9:1) to give 2-(4-((1S)-2-(2-chloro-5-fluorophenyl)-1-methylethylamino)-2-oxo-1,2-dihydropyridin-3-yl)-6-(2-pyrrolidin-1-ylethyl)-6,7-dihydroimidazo[4,5-f]isoindol-5(3H)-one (25 mg, 36%) as pale yellow oil. ESI-MS: m/z (MH+) 549.5. 1H NMR (300 MHz, CD3OD): δ 8.0 (d, J=60.6 Hz, 1H), 7.67 (d, J=52.5 Hz, 1H), 7.33 (m, 1H), 7.15 (m, 2H), 6.89 (m, 1H), 6.09 (m, 1H), 4.66 (m, 2H), 3.98 (m, 2H), 3.68 (m, 1H), 3.30 (m, 2H), 3.15 (m, 6H), 2.02 (m, 4H), 1.43 (d, J=6.60 Hz, 3H).
