When 1,1-bis(methylthio)-2-carbomethoxy-2-cyanoethylene [prepared according to the procedure described in Chem. Ber., 95, 2861 (1962)] is reacted with 2-[(4-methyl-1H-imidazol-5-yl)methylthio]ethylamine according to the procedure of Example 6, Step A, and the resultant 1-carbomethoxy-1-cyano-2-methylthio-2-{2-[(4-methyl-1H-imidazol-5-yl)-methylthio]ethylamino}ethylene treated with propargylamine by the procedure of Example 6, Step B, there is produced 1-carbomethoxy-1-cyano-2-(2-propynylamino)-2-{2-[(4-methyl-1H-imidazol-5-yl)methylthio]ethylamino}ethylene.
