실험 절차

Thus, a mixture of triethyl orthoformate (1equ.) and aniline (2equ.) is heated at reflux for 2 hours. The ethanol evolved during the reaction is then distilled through a fractionating column. The reaction mixture is then allowed to cool, whereupon it solidifies. Recrystallisation of the solid from toluene yields N,N′-diphenyl formamidine in 80% yield.
