Reaction Steps

This ester was prepared by Method C by placing 72.1 g (0.5 mole) of β-naphthol, suspended in 150 ml of benzene, and 0.5 ml of pyridine in the vessel, adding all at once, at room temperature, a solution of 95 g (0.5 mole) of p-chloromethylbenzoyl chloride in 80 ml of benzene, and refluxing this reaction mixture for 6 hours, while passing a weak current of nitrogen through the apparatus. The HCl cleavage began at about 40° C., and at an internal temperature of 50° C., a clear, homogeneous solution had formed. After the end of the reaction time the benzene was substantially removed by distillation. The residue crystallized to a grayish pink crystal mass, the yield of which was quantitative (147.5 g). The raw ester melted at 90°-96° C. It was recrystallized from 2.5 liters of isopropanol with the addition of decolorizing carbon, yielding colorless, pearly, shiny flakes of a melting point of 102°-103.5° C.
