Reaction Steps

A solution of the product of Example 1, step (b), 1.38 g, 0.0050 moles, was dissolved in 20 ml of water. The solution was gradually treated with sodium carbonate, 0.84 g, 0.0100 moles, and cooled to 0° C. A solution of 4chlorobenzoyl chloride, 0.96 g, 0.0053 moles, in 10 ml of tetrahydrofuran was added. A white solid developed after stirring for 65 hours, and was filtered. The filtered product was then taken up in 20 ml of isopropanol and 1 ml of concentrated hydrochloric acid was added. The mix was then brought to a volume of 500 ml with ether and crystals developed. The crystals were filtered and washed with 20 ml of ether (twice) and the product was dried in a vacuum oven, yielding N-(3-(((4-chlorophenyl)carbonyl)amino)phenyl)-1-pyrrolidinecarboximidamide monohydrochloride. Yield: 1.15 g, m.p. 247-250° C.
