Procedure

N-(6-Chloro-5-methylpyridin-2-yl)-1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)cyclopropanecarboxamide (163 mg, 0.444 mmol) was dissolved in 1,2-dimethoxyethane (4.0 mL) in a reaction tube. 2,2,2-Trifluoro-1-(3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)ethanone (200 mg, 0.666 mmol), aqueous 2 M sodium carbonate (0.444 mL), and (Ph3P)4Pd (26 mg, 0.022 mmol) were added and the reaction mixture was heated at 120° C. under N2 atmosphere for 30 minutes in the microwave. The resulting material was cooled to room temperature, filtered, dried over Na2SO4, and concentrated under reduced pressure. The residue was purified by column chromatography on silica gel (0-30% ethyl acetate in hexane) to yield 1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)-N-(5-methyl-6-(3-(2,2,2-trifluoroacetyl)phenyl)-pyridin-2-yl)cyclopropanecarboxamide. ESI-MS m/z calc. 522.1. found 523.5 (M+1)+. Retention time 1.92 minutes.
