Procedure

A 20 mL vial was charged with 3-(2-bromo-4-fluorophenoxy)-5-(3-methoxyphenylthio)-N-(4-(piperidin-4-yl)thiazol-2-yl)pyridin-2-amine (40 mg, 0.068 mmol), triethylamine (0.0190 mL, 0.14 mmol), and CH2Cl2 (2 mL). Ac2O (0.008 mL, 0.082 mmol) was added and the reaction was stirred at room temperature for 10 minutes. The reaction was partitioned between CH2Cl2 and saturated aqueous sodium bicarbonate. The organic layer was dried with sodium sulfate, filtered and concentrated to afford the title compound (38.2 mg, 84.2% yield) as a white solid after HCl salt formation. 1H NMR (d6-DMSO) δ 11.20 (bs, 1H), 8.17 (d, 1H), 7.74 (m, 1H), 7.31 (m, 2H), 7.21 (t, 1H), 6.93 (d, 1H), 6.78 (m, 1H), 6.74 (s, 1H), 6.71 (m, 2H), 4.43 (d, 1H), 3.87 (d, 1H), 3.69 (s, 3H), 3.14 (m, 1H), 2.86 (m, 1H), 2.64 (m, 1H), 2.01 (s, 3H), 1.95 (m, 2H), 1.58 (m, 1H), 1.45 (m, 1H). Mass spectrum (apci) m/z=631.4 (M+H—HCl).
