A chemospecific one-pot synthesis of easily isolable 2-acetoxyindole-3-carbonitriles was described. The intermediate 2-oxindole-3-carbonitriles successfully prepared from 2-cyano diazoacetanilides without isolation were treated with acetyl chloride and triethylamine to give 2-acetoxyindole-3-carbonitriles. The developed one-pot approach showed broad substrate scope.
