Potassium Iodide → 2-[(2-amino-1,3-thiazol-4-yl)methoxy]-1H-isoindole-1,3(2H)-dione

Participants

Reaction Steps

To a solution of 2-hydroxy-1H-isoindole-1,3(2H)-dione (4.13 g, 15.0 mmol) in acetonitrile (150 mL) were added 4-(chloromethyl)-1,3-thiazol-2-amine hydrochloride (50.1 g, 337 mmol), cesium carbonate (210 g, 643 mmol) and potassium iodide (2.54 g, 15.3 mmol). The heterogenous mixture was stirred at room temperature for 16 h. The reaction mixture was diluted with water, the insolubles were filtered off, rinsed with water and dried over night to afford 2-[(2-amino-1,3-thiazol-4-yl)methoxy]-1H-isoindole-1,3(2H)-dione as a colourless solid [36.0 g, yield 43%; HPLC/MS: m/z=276 (M+H); log P(HCOOH)=0.74].
