2-[[2-(2-Furanyl)ethyl]thio]ethyl-1H-isoindole-1,3(2H)-dione (0.5 g), dimethylamine hydrochloride (0.27 g) and paraformaldehyde (0.102 g) were heated together under reflux in ethanol. After 5 hr further dimethylamine hydrochloride (0.27 g) and paraformaldehyde (0.102 g) were added and the heating continued for a further 16 hr. Solvent was removed, the residue basified and extracted with ethyl acetate to give an oil which after column chromatography (silica/methanol) gave 2-[2-[[2-[5-(dimethylamino)methyl-2-furanyl]ethyl]thio]ethyl]-1H-isoindole-1,3(2H)-dione as a pale oil (0.43 g).
