A mixture of 2,6-dichloro-N-(pyridin-3-ylmethyl)nicotinamide (20.4 g, 72.3 mmol), 3-fluorophenethyl amine (11.1 g, 79.5 mmol), K2CO3 (20 g 145 mmol) and DMF (200 mL) was stirred at 100° C. for 10 hours. The mixture was diluted with ethyl acetate (2×300 mL) and washed with saturated ammonium chloride, sodium bicarbonate and brine. The organic layers were combined, dried (MgSO4) and concentrated. The residue was purified by silica gel chromatography to give 6-chloro-2-(3-fluorophenethylamino)-N-(pyridin-3-ylmethyl)nicotinamide (12.6 g, 46%). LRMS (M+H+) m/z 385.1.
