反応手順
A solution of 5-amino-3-cyano-1-(2,6-dichloro-4-trifluoromethylphenyl)-4-trifluoromethylthiopyrazole (500 g) in triethyl orthoformate was treated with concentrated hydrochloric acid (10 ml) and heated at 50° C. After 8 hours the reaction mixture was evaporated to give a solid which was washed (heptane) and air-dried to give 3-cyano-1-(2,6-dichloro-4-trifluoromethylphenyl)-5-ethoxymethylideneamino-4-trifluoromethylthiopyrazole (217 g), m.p. 68° C.
