Sodium hydride/60 percent oil dispersion (0.72 mg, 18 mmol) was added in portions to a slurry of tyramine (2.1 g, 15 mmol) in anh. DMF (25 mL). After 15 minutes, 2-chloro-5-(trifluoromethyl)pyridine (2.9 g, 16 mmol) was added neat and the reaction heated to 50° C. for 3 hours. After cooling, the reaction was poured into water (100 mL) and extracted with ethyl acetate (3×50 mL). The organic portions were combined and washed with brine (50 mL) and dried (Na2SO4). Filtration and removal of solvent left a brown residue that partially solidified. This was triturated in minimal ethyl acetate and collected by filtration, leaving product as a white solid, 3.0 g, 10.6 mmol, 71 percent yield.
