ABSTRACT:
Pyridinylurea compounds of the formula ##STR1## and acid addition salts thereof; wherein R is cyclo alkyl, alkenyl, or an alkyl group optionally substituted with halogen, hydroxy, cycloalkyl, alkoxy, dialkylamino or phenyl; R.sup.1 is hydrogen or alkyl; R and R.sup.1 together with the nitrogen atom of the NRR.sup.1 group optionally define a heterocycle containing 4 to 6 ring carbon atoms; X is hydrogen, halogen, haloalkyl, alkoxy, alkylthio or alkylsulfonyl; Y is hydrogen, halogen, haloalkyl, alkoxy, alkylthio or alkylsulfonyl; and wherein the NHCONRR.sup.1 group is bonded to the pyridinyl ring in the 3- or 4-position; provided that at least one of X and Y is other than hydrogen and when both R and R.sup.1 are alkyl, R is 1,1-dimethylethyl or cyclopentyl and R.sup.1 is methyl.
