Procedure

A 4N solution of HCl in 1,4-dioxane (1.1 ml, 4.3 mmol) was added to a stirring solution of 1,1-dimethylethyl 4-[5-(2-chloro-4-pyrimidinyl)-4-(3-{[(2,5-difluorophenyl)sulfonyl]amino}-2-fluorophenyl)-1,3-thiazol-2-yl]-1-piperazinecarboxylate (0.36 g, 0.54 mmol) in DCM (8 mL) and MeOH (1 mL) at rt. The reaction was allowed to stir overnight. LCMS analysis indicated complete consumption of the starting material. The volatiles were removed in vaccuo to afford the HCl salt of the desired product of Step C (0.40 g, 100% yield) which was carried forward without further purification. MS (ES+): 568 [M+H]+.
