Reaction Steps

To a stirred suspension of the product of step (a) (1.7 g; 0.0052 moles) in 30 ml of chlorobenzene was added a catalytic amount of 4-dimethylaminopyridine. To this was added 1-pyrrolidinecarbonitrile (1.2 ml; 0.016 moles) and the reaction then heated to reflux for 6 hours. The reaction was then cooled and the solvent decanted. To the residue was added 100 ml of 2N sodium hydroxide. The aqueous phase was then extracted 3×75 ml of chloroform and the organic extract was dried over magnesium sulphate. Evaporation of the solvent gave a white solid which was the dissolved in hot isopropanol 5 ml, and 100 ml ethyl acetate. Upon cooling a white solid crystallized and was collected by filtration. The above compound was dried at 70° C. for 72 hours to give N-(4(3-((phenylamino)carbonyl)propyl)phenyl)-1-pyrrolidinecarboximidamide, M.P.164°-165° C.
