To 1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)cyclopropanecarbonyl chloride (91 mg, 0.35 mmol) and tert-butyl 3-(2-amino-5-methylpyrimidin-4-yl)benzoate (50 mg, 0.175 mmol), pyridine (2 mL) was added. The reaction was heated at 90° C. for twenty four 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 tert-butyl 3-(2-(1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)cyclopropanecarboxamido)-5-methylpyrimidin-4-yl)benzoate. ESI-MS m/z calc. 509.18. Found 510.5 (M+1)+. Retention time 2.22 minutes
