In addition, there was also present in the flask 100 grams of triethylamine and 200 cc. of benzene. When the mixture has reached the desired reduced temperature, decanesulfenyl chloride is slowly added dropwise accompanied by continuous stirring. Upon completion of the addition of the decanesulfenyl chloride, the mixture is stirred for an additional period of 1 hour and then allowed to warm to room temperature. Upon standing the desired product comprising N,N'-di-p-tolyl-N-decylthioformamidine crystallizes, is filtered, washed and recovered.
