Procedure

The product of Step 1 (10 mg, 0.018 mmol), N-hydroxybenzotriazole (5.4 mg, 0.035 mmol), diisopropylethylamine (31 μL, 0.18 mmol), and 1-ethyl-3-(3-dimethylaminopropyl)-carbodiimide hydrochloride (6.7 mg, 0.035 mmol) were taken-up in N,N-dimethylformamide (0.5 mL). Ammonium chloride (6.6 mg, 0.12 mmol) was added in one portion, and the resulting mixture was stirred overnight at room temperature. The resulting mixture was directly purified via reverse phase HPLC (10-80% acetonitrile/water+0.05% TEA modifier). Desired fractions were combined, diluted with ethyl acetate and washed with saturated aqueous sodium bicarbonate (1×) and 10% aqueous ammonium hydroxide (1×). The organic layer was dried over magnesium sulfate, filtered, and concentrated in vacuo to afford 2-{[2-({3-methyl-5-[2-(1,1,1-trifluoro-2-hydroxypropan-2-yl)-1,3-thiazol-5-yl]phenyl}amino)pyrimidin-4-yl]oxy}acetamide (6 mg, 0.013 mmol, 76% yield) as a white solid.
