Reaction Steps

The ester was prepared by Method C only, by dissolving 47 g (0.5 mole) of phenol in 60 ml of benzene in the apparatus used in the preparation of the para compound, adding 0.5 ml of absolute pyridine as catalyst, and then adding 95 g (0.5 mole) of undiluted o-chloromethylbenzoyl chloride drop by drop at 55° to 60° C. over a period of about 1 hour, the mixture being stirred for another 4 hours at the refluxing temperature to complete the reaction. The benzene was then distilled out of the clear, light red solution thus obtained. The viscous oily, clear, red residue obtained in a quantitative yield crystallized after standing for a while at -15° C. The crystal mass thus obtained was ground in a chilled mortar with about 100 ml of intensely cooled isopropanol; the undissolved portion was removed by suction filtering and washed with 100 ml of isopropanol chilled to -20° C. After drying, 87 g (70%) was obtained of a colorless crystallizate with a melting point of 39°-41° C. For the analysis, 15 g was dissolved at 35° C. in 125 ml of isopropanol and set aside to crystallize at -20° C. 12.7 g of colorless needles was obtained with a melting point of 39°-41° C.
