The regioselective introduction of two carbons into the N-Methyl-2-cyclopentadienyl-propylamine framework 8 was achieved in two steps involving an N-formylation followed by an aminomethylenation of the β position of the cyclopentadiene ring by reaction with DMF acetal. Subsequent intramolecular Vilsmeier-Haack cyclisation produced the formyl-aminofulvene intermediate 9 which was converted to aminodiene
