A solution of 2-(2-aminoethylthiomethyl)-6-(dimethylaminomethyl)benzofuran (Example 1, Step E) (2.6 g., 0.01 mole) and allyl isothiocyanate (1.1 g., 0.011 mole) in acetonitrile (15 ml.) is kept at 25°-27° C. for 16 hours. The solvent is evaporated and the residual oil chromatographed (silica gel/5% methanol in chloroform) to yield N-[2-(6-dimethylaminomethyl-2-benzofuranylmethylthio)ethyl]-N'-(2-propenyl)thiourea.
