Procedure

A solution of 7-{[2-(tert-butoxycarbonyl)pyridin-4-yl]oxy}-1,2,3,4-tetrahydronaphthalene-2-carboxylic acid (0.653 g, 1.77 mmol), 3-amino-5-(trifluoromethyl)-benzonitrile (0.362 g, 1.94 mmol), and DMAP (0.238 g, 1.94 mmol) in DCM (10 mL) was cooled to 0° C. To this solution was added EDCI (0.339 g, 1.77 mmol). The reaction mixture was allowed to stir and warm to rt overnight. The reaction mixture was diluted with EtOAc, washed with 1N HCl and sat. aq. NaHCO3, and concentrated. The residue was purified by column chromatography to give tert-butyl 4-{[7-({[3-cyano-5-(trifluoromethyl)phenyl]-amino}carbonyl)-5,6,7,8-tetrahydronaphthalen-2-yl]oxy}pyridine-2-carboxylate (0.750 g, 79%). LCMS: (FA) ES+ 538.6.
