Ethyl chloroacetate → HCID 53739137, compound

Participants

Reaction Steps

To a mixture of 2-oxo-5-amino-6-chloroindoline (3.2 g), potassium carbonate (4.8 g) and acetone (60 ml) was added dropwise ethyl chloroacetate (3.2 g) at ambient temperature. The reaction mixture was refluxed with stirring for 4 hours and then filtered under warm condition. The filter cake was washed with acetone. The combined filtrate and washings were concentrated under reduced pressure to give a residue, which was purified by a column chromatography on silica gel to give crystalline ethyl 2-oxo-5-amino-6-chloro-1-indolineacetate (0.9 g).
