The synthesis is achieved in three steps. The first step is the preparation of N,N′-diphenyl formamidine (by the reaction of aniline with triethyl orthoformate). This intermediate is then further reacted with triethyl orthoformate to produce ethyl N-phenylimidoformate. The final step is the reaction of ethyl phenylimidoformate with 4-aminostyrene to give the product.
