Reaction Conditions

Reaction Steps

6.85 g (0.055 mol) of benzyl mercaptan are dissolved in 150 ml of dimethylformamide. The batch is then cooled to 0° C. and 15.2 g (0.11 mol) of potassium carbonate are added. 10.6 g (0.050 mol) of 2,3-dinitrobenzoic acid are then added in portions at from 0° to 5° C. and the internal temperature is afterwards raised to room temperature over a period of 24 hours. The reaction mixture is then poured onto ice/water and acidified with hydrochloric acid. The resulting product is filtered, washed with water and dried. Yield: 11.8 g (82% of the theoretical yield); m.p. 152°-153° C.
