Procedure

13.6 G. 3-cyanodibenzo[b,f]thiepin-5,5-dioxide are refluxed for 2.5 hours in a mixture of 20 cc. 10% aqueous sodium hydroxide solution and 20 cc. ethanol. The mixture is diluted with water and acidified with concentrated HCl. The acid precipitates as a white solid. The yield of acid, m.p. 268° C.-270° C. is 1.38 g. (94.6%).
