NEW MATERIAL: A compd. of formula I (where R 1 is H, halogen, etc.; R 2 is H, 1-2 C alkyl, etc.; R 3 , R 4 are each H, 1-2 C alkyl; R 5 , R 6 are each H, halogen, 1-5 C alkyl; R 7 is H, 1-2 C haloalkyl, etc.; R 8 , R 9 are each H, halogen, 1-2 C alkoxy, etc.; R 10 is H, halogen, etc.; R 11 is H, 1-6C alkyl, etc.; R 12 is H, halogen; Y is CH-, =N-). n EXAMPLE: 5-Chloro-2-[(4-chlorophenylsulfonyl)-amino]-benzoic acid [4-(4- trifluoromethyl-6-cyclopropylpyrimidin-2-yloxy)-anilide]. n USE: An anthelmintic. Especially useful for control of nematode, cestode and trematode. n PROCESS: The compd. of formula I is obtd. by reacting a compd. of formula II with benzenesulfonic acid halide of formula III (where X is halogen) at (-20)-150°C under the existence of a base, (e.g. pyridine), in a aprotic solvent. n COPYRIGHT: (C)1991,JPO |
