Procedure

To a stirred solution of N-(5-chloropyridin-2-yl)-2-aminobenzamide (0.5 g, 1.79 mmol) and Boc-isonipecotic acid (0.41 g, 1.79 mmol) in N,N-dimethylformamide (30 mL) was added 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (0.69 g, 3.58 mmol). After stirring for 15 h, the solvent was removed in vacuo. The residue was partitioned between ethyl acetate and water, and the layers separated. The organic phase was washed with saturated aqueous sodium chloride, dried (magnesium sulfate), filtered, and concentrated in vacuo. The solid was suspended in ether, sonicated, and filtered to give 0.147 g (18%) of a tan solid.
