실험 절차

288 parts of α-naphthol, 411 parts of p-phenetidine and 10 parts of triphenyl phosphite are mixed and heated to 220° C. At this temperature, the elimination of water commences. In the course of 8 hours, the reaction temperature rises to 250° C, at which stage the reaction has ended. 36 parts of water are removed. After removing excess p-phenetidine, N-p-ethoxy-phenyl-α-naphthylamine distils at a boiling point of 233° - 235° C/5 mm Hg. 510 parts of end product of melting point 73° - 75° C are obtained. This corresponds to a yield of 97% of theory.
