Synthesis of 3-Alkyl-3-bromo-1-ethoxycarbonyl-1,3-dihydro-2H-indol-2-ones

Abstract
3-Alkyl-1,3-dihydro-2H-indol-2-ones 1 are converted to the coresponding 2-ethoxycarbonyloxy derivatives 2 by reaction with ethyl chloroformate in the presence of triethylamine. Bromination of 2 affords the title compounds in 73-93% yield.
