Versuchsvorschrift
5-[5-(Dimethylamino)methyl-2-furanyl]pentanamine (0.5 g) and methylisothiocyanate (0.25 g) were stirred in acetonitrile at room temperature for 24 hr. Solvent was removed and the product purified by column chromatography (silica/methanol) to give after trituration with ether N-[5-[5-(dimethylamino)methyl-2-furanyl]pentyl]-N'-methylthiourea as off-white crystals m.p. 66°-69°.
