Participants

Reaction Steps

2-[(2-Chloro-1,3-thiazol-5-yl)methoxy]-1H-isoindole-1,3(2H)-dione (Bionet, 5.0 g), was suspended in ethanol (120 ml) and hydrazine monohydrate (0.83 ml) was added. The mixture was heated to reflux and stirred at this temperature for 4 hours. The mixture was cooled to room temperature and the solid material was removed by filtration. The filtrate was evaporated under reduced pressure. The residue was re-suspended in diethyl ether (400 ml) and 4M HCl in dioxane (4.25 ml) was added. The solid material was isolated by filtration and dried under vacuum, and gave the title compound (3.3 g). 13C-NMR (DMSO-d6) δ 152.5, 143.3, 133.5, 66.9.
