In a related method, Claisen condensation of ethyl formate with cyclopropaneacetonitrile (X), followed by acetylation of the intermediate potassium enolate (XII) with Ac2O, furnished the (acetoxy)acrylonitrile (XIII). This was finally cyclized with amidine (IX) in the presence of Et3N in refluxing toluene.
