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 (0.028 mL, 0.20 mmol), and CH2Cl2 (2 mL). 2-(Dimethylamino)acetyl chloride hydrochloride (12.9 mg, 0.0817 mmol) was added and 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. The residue was purified on silica gel (15% MeOH in EtOAc with 0.3% ammonia) to afford the title compound (35.6 mg, 70.1% yield) after HCl salt formation. 1H NMR (d6-DMSO) δ 11.15 (bs, 1H), 9.60 (bs, 1H), 8.17 (d, 1H), 7.75 (m, 1H), 7.32 (m, 2H), 7.21 (t, 1H), 6.94 (d, 1H), 6.79 (m, 1H), 6.75 (s, 1H), 6.71 (m, 2H), 4.42 (d, 1H), 4.31 (qd, 2H), 3.69 (s, 3H), 3.19 (t, 1H), 2.93 (m, 1H), 2.82 (m, 6H), 2.04 (d, 2H), 1.64 (m, 1H), 1.52 (m, 1H). Mass spectrum (apci) m/z=674.3 (M+H-2HCl).
