Procedure
7-(2-{1-[2-(4-Cyanophenoxy)ethyl]ureido}ethyl)-9-oxa-3,7-diazabicyclo-[3.3.1]nonane-3-carboxylic acid tert-butyl ester (6.44 g; see step (i) above) was added to a solution of HCl-saturated, dry dioxane (300 mL) at 0° C. The reaction was then stirred at rt for 1 hr. The resulting precipitate was filtered under N2, washed with dry ether and then dried under vacuum to provide the title compound. Yield: 6 g.
