167 g of 3,5-dibenzyloxybenzoic acid and 400 ml of redistilled thionyl chloride were refluxed on an oil bath for one hour. Excess thionyl chloride was distilled off at reduced pressure, and the remaining mass crystallized. The product was recrystallized from petroleum ether (B.p., 60°-85° C.) : M.P. 73°-74° C.
