Procedure

To 1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)cyclopropanecarbonyl chloride (369 mg, 1.42 mmol) and 4-(6-methoxypyridin-3-yl)-5-methylpyrimidin-2-amine (153 mg, 0.71 mmol), pyridine (4 mL) was added. The reaction was heated at 90° C. for three and a half hours. The pyridine was evaporated under reduced pressure. The resulting mixture was dissolved in ethyl acetate and filtered. The filtrate was washed with saturated aqueous NaHCO3 (×3). The organic layer was dried over anhydrous Na2SO4 and evaporated under reduced pressure. The crude product was purified by column chromatography on silica gel to yield 1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)-N-(4-(6-methoxypyridin-3-yl)-5-methylpyrimidin-2-yl)cyclopropanecarboxamide. ESI-MS m/z calc. 440.13, found 441.5 (M+1)+. Retention time 1.72 minutes.
