Procedure

A suspension comprising CDI (2.29 g, 14 mmol) and triethylamine (3.8 ml, 27 mmol) in dry DCM (20 ml) is treated portionwise over 5 minutes with 3,4,5,6-tetrahydro-2H-[1,2′]bipyridinyl-4-ylamine dihydrochloride (prepared using the procedure described in international patent application WO 01/94368) (2.88 g, 13 mmol). The reaction mixture is stirred at room temperature for 4.5 hours to yield the title compound as a 0.43 M solution in DCM.
