Procedure

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 0.71 ml of isobutyl chloroformate in 10 ml of tetrahydrofuran was added. After 16 hours the mixture was diluted with water to 100 ml and washed with 20 ml of chloroform. This solution was then made basic with 50% aqueous sodium hydroxide and extracted with 20 ml chloroform (twice). The chloroform layer was dried over potassium carbonate, filtered and the solvent was driven off by vacuum evaporation. The remaining oil was dissolved in 20 ml of isopropanol and 1 ml of concentrated aqueous hydrochloric acid was added. The solution was then made up to 250 ml with ether. Crystals developed and were washed with 10 ml of ether (twice) and dried in a vacuum oven overnight to yield N-(3-(((2-methylpropyloxy)carbonyl)amino)phenyl)-1-pyrrolidinecarboximidamide monohydrochloride. Yield: 1.1 g, m.p. 233°-235 ° C.
