Reaction Steps

To a stirred solution of 5-hydroxyindolin-2-one (1 g, 6.70 mmol) in 2-Propanol (10 mL) was added DBU (1.52 mL, 10.06 mmol) and ethyl bromoacetate (1.12 mL, 10.06 mmol) at room temperature. The reaction mixture was refluxed at 80° C. for 12 h. After completion of the reaction as monitored by TLC, the reaction mixture was concentrated and water (100 mL) was added. The solid which precipitated was filtered and dried to yield ethyl 2-((2-oxoindolin-5-yl)oxy)acetate as an off white solid (0.75 g, 47.6%) LCMS: RT 0.67 min. LCMS (ES-API), m/z 236.0 (M+H).
