A solution of 5-bromo-2-chloro-3-(5-(2,3-dichlorophenyl)thiazol-4-yl)pyridine (520 mg, 1.24 mmol) and p-methoxybenzyl amine (373 mg, 2.72 mmol) in DME (12 mL) was stirred at 80° C. for 48 hours. The reaction mixture was concentrated and the residue purified by silica gel chromatography (0-25% EtOAc/hexanes) to give N-(4-methoxybenzyl)-5-bromo-3-(5-(2,3-dichlorophenyl)thiazol-4-yl)pyridin-2-amine as a pale yellow solid [631 mg, 85% yield; LC-MS, M+H=519.9; 1H-NMR (300 MHz, CDCl3) 8.85 (1 H, s), 8.00 (1 H, d, J=2.3 Hz), 7.45 (1H, dd, J=1.9, 7.6 Hz), 7.10-7.17 (4 H, m), 7.01 (1 H, d, J=2.4 Hz), 6.77 (1 H, t, J=6.7 Hz)].
