Reaction Conditions

Reaction Steps

5.6 g (0.03 mol) of 5-chloro-3-trifluoromethyl-1,2,4-thiadiazole are added to a mixture which comprises 4 g (0.03 mol) of hydroxyacetic acid diethylamide, 1.9 g (0.03 mol) of potassium hydroxide powder and 80 ml of isopropanol and has been cooled to -10° C. The reaction mixture is stirred for 10 hours at -10° C. and poured into water, and the product is filtered off under suction. 4 g (47% of theory) of (3-trifluoromethyl-1,2,4-thiadiazol-5-yl)-oxyacetic acid diethylamide are obtained in the form of white crystals of melting point 60° C.
