We have recently reported2 our finding that the reaction of N,Ndimethyl-N'-nitroso-N'-(2,3-diphenyl-2-cyclopropenyl)urea (I) with base in the presence of excess dimethyl fumarate followed by acid work-up gives the methylenecyclopropene3 II according to the following equation.

## Abstract An attempt to synthesize the Tenidap isomer **13** was performed starting from 2‐ethoxy‐5‐chloroindole (**9**). The acylation and carbamoylation reactions of **9** led to the expected intermediate **12**, however the hydrolysis of **12** in acidic or alkaline media did not yielded the e
