実験手順

17 g (0.07 mol) of 5-chloro-3-trichloromethyl-1,2,4-thiadiazole are added to a stirred mixture which comprises 11 g (0.07 mol) of hydroxyacetic acid 2-methylpiperidide, 4.5 g (0.07 mol) of potassium hydroxide powder and 100 ml of isopropanol and has been cooled to -10° C. The reaction mixture is stirred for 20 hours at -10° C. and then poured into water, and the product is filtered off under suction and washed with water. 18 g (72% of theory) of (3-trichloromethyl-1,2,4-thiadiazol-5-yl)-oxyacetic acid 2-methyl-piperidide are obtained in the form of a white powder of melting point 88° C.
