Procedure

To a solution of 1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)-N-(6-(2-methoxypyrimidin-5-yl)-5-methylpyridin-2-yl)cyclopropanecarboxamide (88 mg, 0.20 mmol) in CH3CN (2 mL) was added TMSI (80 mg, 0.40 mmol). The mixture was heated at 75° C. for 4 hours. The mixture was partitioned between ethyl acetate and H2O, and the aqueous layer was extracted with ethyl acetate (3×). The combined organic layers were washed with brine, dried over MgSO4, and concentrated under reduced pressure. The residue was purified by preparative LC/MS to yield 1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)-N-(6-(2-hydroxypyrimidin-5-yl)-5-methylpyridin-2-yl)cyclopropanecarboxamide. MS (ESI) m/e (M+H+) 427.3.
