Procedure

5,6-Diamino-2-(2-(dimethylamino)ethyl)isoindoline-1,3-dione (0.47 g, 1.88 mmol) was dissolved in MeOH (30 mL) and acetic acid (10 mL). 2-Methoxy-4-((1-phenylpropan-2-yl)oxy)nicotinaldehyde (0.51 g, 1.88 mmol) was added under air at rt. The reaction mixture was stirred at rt under air overnight. The volatile was removed. The residue was subjected to column chromatography (silica-gel, CH2Cl2/MeOH=17/3 v/v) to give a white solid product, 0.65 g, 69.2% yield. MS: 500.3 [M+H]+. 1H-NMR (DMSO-d6, 500 MHz): δ 13.23 (s, 1H), 8.20 (d, 1H, J=6.0 Hz), 8.12 (s, 1H), 7.95 (s, 1H), 7.09-7.07 (m, 1H), 7.11-7.95 (m, 5H), 4.84-4.81 (m, 1H), 3.82 (s, 3H), 3.72 (t, 2H, J=6.5 Hz), 2.78 (d, 2H, J=6.0 Hz), 2.53 (t, 2H, J=6.5 Hz), 2.19 (s, 6H), 1.17 (d, 3H, J=6.0 Hz).
