Procedure

A mixture of 2-(4-chloro-2-oxo-1,2-dihydropyridin-3-yl)-6-(2-(dimethylamino)ethyl)-4-methylimidazo[4,5-f]isoindole-5,7(1H,6H)-dione (0.54 g, 1.35 mmol), 1-(2,3,5,6-tetrafluorophenyl)propan-2-amine (0.34 g, 1.62 mmol), Hunig,s base (0.87 g, 6.75 mmol), and 12 mL of anhydrous 1-butanol was heated at reflux for 13-14 h under an argon atmosphere. Product was purified by a silica gel column using methylene chloride and methanol (9:1 v/v) as eluent to afford 0.33 g of the designed compound as yellow solid. 1H NMR (300 MHz, DMSO-d6) δ 13.33 (s, 1H, NH), 11.29 (br s, 1H, NH), 11.00 (d, J=5.7 Hz, 1H, NH), 7.97 (s, ArH), 7.73-7.70 (m, 1H, ArH), 7.40 (d, J=7.6 Hz, 1H, ArH), 6.21 (d, J=7.6 Hz, 1H, ArH), 4.32-4.28 (m, 1H, CH), 3.65 (t, J=6.3 Hz, 2H, CH2), 3.08 (d, J=5.1 Hz, 2H, CH2), 2.72 (s, 3H, CH3), 2.19 (S, 6H, 2×CH3); 1.36 (d, J=6.3 Hz, 3H, CH3), 1.11 (t, J=6.3 Hz, 2H, CH2); Mass (ESI, negative) m/z 568.8 [M−H]−.
