Reaction Steps

A mixture comprising ((S)-1-Pyridin-2-yl-pyrrolidin-3-ylamine dihydrochloride (0.242 g, 1.02 mmol), TEA (0.2 ml) in DCM (10.2 ml) is treated with CDI (0.364 g, 2.26 mmol). The reaction mixture is stirred at room temperature for 2 hours to yield the titled compound as 0.1 M solution in DCM. This solution consists of the imidazole-urea intermediate together with variable amounts of the corresponding isocyanate and imidazole. This solution is used in the subsequent steps since the imidazole-urea intermediate and isocyanate intermediate are equally suitable as precursors to ureas.
