Reaction Steps

p-Cyanobenzamide (73.0 g, 0.5 mol) which has a purity of 99% or more and ethanol (657.0 g) were placed in a 2 l-separable flask, and the mixture was allowed to react at 78° C. for 19 hours while a 95% sulfuric acid (51.6 g) was added thereto with stirring. Gas chromatographic analysis revealed that the reaction mixture contained 66.5 g of ethyl p-cyanobenzoate (yield 76%).
