Dissolve 4-bromo-phenylacetic acid (660 mg, 3.07 mmol) and 6-methyl-4-trifluoromethyl-pyridin-2-ylamine (500 mg, 2.84 mmol) in 10 mL dry THF. Add 4-methyl morpholine (345 mg, 0.375 mL, 3.4 mmol), stir a few minutes under nitrogen atmosphere, then add DMTMM (865 mg, 3.12 mmol) and stir the pale yellow slurry overnight. Dilute slurry with 90 mL EtOAc, wash twice each with saturated aqueous NaHCO3 and aqueous saturated sodium chloride, then dry the organic layer over MgSO4 and concentrate to give an ivory crystalline solid. Purify this solid on a 120 g silica cartridge with 0→5% EtOAc in dichloromethane to give 660 mg (62%) of the title compound as a white crystalline solid. LCMS (ES) m/z 373/375 (M+1).
