Title compds. (I; X = CN, NO2, NCCH2, mercapto, alkylthio alkylsulfinyl, alkylsulfonyl, alkylsulfomyl, CF3 or their acid-addition salts), useful as rodenticides, were prepd. by reaction of 3-pyridinemethanol with Ph isothiocyanates(II) at 0-50≦̸C for >2 hr in anhydrous inert solvent. Thus, a soln. of II in glyme was converted to the Na salt with NaH in 2 hr, then P-cyanophenylisothiocyanate in glyme was added. The mixt. was filtrated and recrystallized to give 3-pyridyl N-(4-cyanophenyl thiocarbamate).
