Reaction Steps

A 20 mL vial was charged with tert-butyl 4-(2-(3-(2-bromo-4-fluorophenoxy)-5-(3-methoxyphenylthio)pyridin-2-ylamino)thiazol-4-yl)piperidine-1-carboxylate (100 mg, 0.145 mmol) and CH2Cl2 (2 mL). TFA (2 mL) was added and stirred at room temperature for 5 minutes. The reaction was poured into water and diluted with CH2Cl2. Solid Na2CO3 added slowly to neutralize the TFA. The aqueous layer was extracted and dried to afford the title compound (88 mg, 103% yield). 1H NMR (d6-DMSO) δ 8.16 (d, 1H), 7.74 (m, 1H), 7.30 (m, 2H), 7.21 (t, 1H), 6.92 (d, 1H), 6.78 (m, 1H), 6.70 (m, 3H), 3.69 (s, 3H), 3.17 (m, 2H), 2.77 (m, 3H), 2.01 (m, 2H), 1.62 (m, 2H). Mass spectrum (apci) m/z=587.2, 589.2 (M+H).
