Procedure
A mixture of 6.0 g. of p-[2,2-bis(p-chlorophenyl)acetamido]benzoic acid, ethyl ester, 920 mg. of potassium hydroxide, and 50 ml. of 95% ethanol is stirred at 75° C. for 9 hours, cooled, diluted with 100 ml. of water, and the pH is adjusted to 2.0 with 37% hydrochloric acid. The precipitate is collected, washed with water, dried and recrystallized from 100 ml. of ethanol, giving 2.78 g. of the desired product as colorless crystals, m.p. 272°-274° C.
