Procedure

A solution of N-cyano-N'-[2-((4-methyl-5-imidazolyl)methylthio)ethyl]-S-methylisothiourea (2.69 g) and 2-phenylethylamine (7.2 g) in acetonitrile (50 ml) was heated under reflux for 24 hours. Following concentration and other extraction to remove excess 2-phenylethylamine the crude product was chromatographed on a column of silica gel and eluted with ethyl acetate-isopropyl alcohol (4:1). Recrystallisation from ethanol-ether afforded the title compound (1.4 g) m.p. 135°-136°.
