To a stirred solution of N"-cyano-N-(2-mercaptoethyl)-N'-methylguanidine (1.0 g) and sodium hydride (0.152 g) in dry dimethylformamide (4 ml) at room temperature was added slowly a solution of 2-(5-chloromethyl-2-furanylmethyl)-1H-isoindole-1,3(2H)-dione (1.74 g) in dry dimethylformamide (8 ml). After stirring for 2 hr in the solution was evaporated to dryness and the oily residue suspended in an ethyl acetate (25 ml)-water (20 ml) mixture. The solid residue was filtered and crystallised from methanol to give the title compound (1.4 g) m.p. 179°-182°.
