実験手順

The compound, 2-(((4-amino-3-chlorophenyl)-thio)methyl)-2-imidazoline p-toluenesulfonate was prepared by refluxing a mixture of 2-chloro-4-cyanomethylthioaniline (10 g), ethylenediamine p-toluenesulfonate (12 g) and 1,2-dichlorobenzene (150 ml). The reaction mixture was cooled and most of the 1,2-dichlorobenzene decanted off, leaving a viscous residue. Water and methylene chloride were added to the viscous residue and the mixture basified. The methylene chloride layer was separated and approximately 10 g of viscous residue obtained. The residue was dissolved in dimethoxyethane and 5 N hydrochloric acid in isopropanol added. Recrystallization from absolute ethanol containing HCl and then from dimethoxyethane gave 2-(((4-amino-3-chlorophenyl)thio)methyl)-2-imidazoline dihydrochloride, m.p. 195°-199° C.
