Reaction Steps

2-(2-Chloro-4-methoxy-5-methylbenzyl)isoindoline-1,3-dione (174 mg, 0.55 mmol) was dissolved in MeOH (30 ml) and hydrazine hydrate (111 mg, 2.21 mmol) and then heated under reflux for 1 hour. The solvent was removed in vacuo and the precipitate was filtered off. The filtrate was evaporated to give a residue, which was chromatographed on a column of silica gel eluting with MeOH-DCM (1:10) to give the title compound (130 mg, 100%) as white solid. 1H NMR (270 MHz, DMSO-d6) δ ppm 2.12 (3H, s), 3.38 (2H, br s), 3.69 (2H, s), 3.78 (3H, s), 6.94 (1H, s), 7.29 (1H, s). MS (ESI) m/z 169 (M+H—NH2)+
