To a solution of 2-chloro-4-[3-(trifluoromethyl)-1H-pyrazol-1-yl]benzeneethanamine hydrochloride (1:1) (i.e. the product of Step C; 300 mg, 1.11 mmol), N-(3-dimethyl-aminopropyl)-N′-ethylcarbodiimide (297 mg, 1.66 mmol), 1-hydroxybenzotriazole (212 mg, 1.66 mmol) and N,N-diisopropylethylamine (0.9 mL, 5.55 mmol) in dichloromethane (15 mL) was added 3-(trifluoromethyl)pyridine-2-carboxylic acid (198 mg, 1.21 mmol), and the resulting mixture was stirred for 12 h. The reaction mixture was washed with water and brine, dried (Na2SO4) and concentrated under reduced pressure. The residue was purified by flash column chromatography on silica gel eluted with 50% ethyl acetate in hexanes to afford the title compound (210 mg) as a brown solid.
