Procedure

A mixture of 3-cyanophenacyl chloride (1.78 g.) and amidinothiourea (1.2 g.) in EtOH (40 ml.) was heated under reflux for 1 hour. The solid precipitate was filtered off, dissolved in hot water (100 ml.) and the solution basified with sodium bicarbonate. The precipitated solid was filtered off and dried to give 3-[2-guanidinothiazol-4-yl]benzonitrile which was used without further purification.
