Participants

Reaction Steps

With continuous stirring and cooling, 4.1 g of α-(chlorothio)-isobutyronitrile are added dropwise at 0° to 10° C. to a solution of 6.97 g of 2-[1-(2,3-dimethylphenoxy)-propyl]-2-imidazoline of the formula ##STR4## and 4 g of triethylamine in 80 ml of toluene. The reaction mixture is stirred for 1 hour at room temperature, then the toluene phase is washed repeatedly with water and dried. The toluene is then evaporated off, affording 1-(2-cyano-prop-2-ylthio)-2-[1-(2,3-dimethylphenoxy)-propyl]-2-imidazoline of the formula ##STR5## in the form of a yellow viscous oil with a melting point of 58°-60° C. The following compounds of the formula I can be obtained by procedures analogous to the one described in this Example: ##STR6##
