Water → 2-[(1,3-Dioxo-1,3-dihydro-2H-isoindol-2-yl)oxy]acetamide

Potassium carbonate (2.67 g, 19.31 mmol) was added to a solution of N-hydroxyphthalimide (3.0 g, 18.39 mmol) in anhydrous DMF (37 mL) at 0° C. The reaction mixture was stirred at 0° C. for 10 min and then at room temperature for 1 h. The reaction mixture was cooled to 0° C. and 2-bromoacetamide (2.79 g, 20.23 mmol) was added. The reaction mixture was stirred at 0° C. for 10 min and then at room temperature overnight. The reaction mixture was poured into rapidly stirring water and the precipitated solid was collected by filtration and dried to afford 2-[(1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl)oxy]acetamide (2.0 g, 49%) as a yellow solid: 1H NMR (300 MHz, CD3OD) δ4.63 (2H, s), 7.85-7.88 (4H, m); ESI MS m/z 221 [C10H8N2O4+H]+.
