Reaction Steps

To a solution of 2-{[5-(trifluoromethyl)pyridin-2-yl]methyl}cyclopentan-1-amine hydrochloride (Intermediate 36; 0.60 g, 2.44 mmol) in DMF (5 ml) was added DIPEA (0.63 g, 4.80 mmol), TBTU (0.94 g, 2.93 mmol) and added 5-methyl-2-(2H-1,2,3-triazol-2-yl)benzoic acid (Intermediate 6; 0.49 g, 2.44 mmol). The reaction was stirred at room temperature for 1 hour and then partitioned between ethyl acetate (50 ml) and water (10.0 ml). The aqueous layer was further extracted with ethyl acetate (50 ml) and the combined organics were concentrated in vacuo. The resulting residue was purified by column chromatography (silica, 0-2% methanol/DCM) to afford the title compound.
