## Abstract The mechanism of the formation of 1‐methyl‐3__H__,9__H__‐pyrano[3,4‐__b__]indol‐3‐one (4) from the corresponding 3‐indolacetic acid 1 is discussed. The suggested mechanism is substantiated by the isolation of a stable intermediate 2 and its transformations in the presence of acetic anhy
