Versuchsvorschrift

2-phenylethylamine (2.4 g.), N,N',S-trimethylisothiourea hydriodide (4.92 g.) and ethanol (70 ml.), were boiled together under reflux for eight hours; methyl mercaptan was evolved. The resulting solution was evaporated to dryness and the residue recrystallised from methanol/ether mixture to yield N,N'-dimethyl-N"-2-phenylethylguanidine hydriodide, melting point 156°-160°C.
