実験手順

Sodium methoxide (2.16 g) was added to a mixture of 2-imino-3-methylthiazolidine hydroiodide (10.0 g) in ethanol (50 ml) and brought to reflux, with stirring. Phenylisothiocyanate (5.4 g) in ethanol (20 ml) was added to the mixture over 5 minutes and the resultant mixture heated under reflux, with stirring, for one hour then cooled in ice. Filteration gave analytically pure product, mpt 169°-170°, which may be recrystallised from isopropanol.
