To 2-chloropyrimidine-4-carboxylic acid (175 mg, 1.104 mmol) in dioxane (2.201 mL) was added 2-[5-(3-amino-5-methylphenyl)-1,3-thiazol-2-yl]-1,1,1-trifluoropropan-2-ol (INTERMEDIATE 17, (334 mg, 1.104 mmol) and acetic acid (69.5 μL, 1.214 mmol). The reaction was heated to 100° C. overnight and was complete by LCMS analysis. The reaction was cooled to room temperature and the solvent was removed under reduced pressure. Remaining acetic acid was azeotroped with toluene (2×5 mL) to yield 2-({3-methyl-5-[2-(1,1,1-trifluoro-2-hydroxypropan-2-yl)-1,3-thiazol-5-yl]phenyl}amino)pyrimidine-4-carboxylic acid as a tan powder.
