Reaction Conditions

Reaction Steps

A mixture of 15.8 g of 4-cyanophenoxyacetonitrile and 23.3 g of ethylenediamine p-toluenesulfonate in 50 ml of 1,2-dichlorobenzene was heated at from about 130°-145° C. for about an hour. After reaction the mixture was cooled, diluted with CH2Cl2 and filtered to obtain the crude product. The crude product was dissolved in boiling absolute ethanol, treated with activated charcoal and filtered through a fluted paper. The filtrate was cooled to 5° C. for 1.5 hours and the crystals which formed removed by filtering. After drying in a vacuum oven, off-white crystals were obtained having a melting point of 190°-192° C. The off-white crystals were put in solution in 200 ml of boiling water and treated with activated charcoal and filtered. The filtrate was cooled to 5° C. for 1 hour and the crystals which formed removed by filtration. Upon drying, the product 2-((4-cyanophenoxy)methyl)-2-imidazoline p-toluenesulfonate was obtained as white crystals, m.p. 196°-198° C.
