A solution of N-(4-methoxybenzyl)-5-bromo-3-(5-(2,3-dichlorophenyl)thiazol-4-yl)pyridin-2-amine (110 mg) and TFA (100 μL) in methylene chloride (2 mL) was stirred at 40° C. overnight. The reaction was concentrated and purified by reversed-phase HPLC to give 5-bromo-3-(5-(2,3-dichlorophenyl)thiazol-4-yl)pyridin-2-amine as a white solid [1.1 mg, 2% yield; LC-MS M+H=519.9; 1H-NMR (300 MHz, methanol-d4) 9.17 (1H, d), 7.95 (1H, d), 7.60-7.63 (2H, m), 7.34-7.35 (1H, m), 7.27 (1H, dd)].
