Procedure

N-(6-Chloro-5-ethylpyridin-2-yl)-1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)cyclopropanecarboxamide (38 mg; 0.10 mmol) was dissolved in 1 mL of 1,2-dimethoxyethane (DME) in a microwave reactor tube. 4-(tert-butoxycarbonyl)phenyl-boronic acid (29 mg, 0.13 mmol), 0.1 mL of an aqueous 2 M potassium carbonate solution, and tetrakis(triphenylphospine)palladium(0) (Pd(PPh3)4, 5.6 mg, 0.0048 mmol) were added and the reaction mixture was heated at 120° C. in a microwave reactor for 20 minutes. The resulting material was cooled to room temperature, filtered, and the layers were separated. The organic layer was concentrated in vacuo to yield tert-butyl 4-(6-(1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)cyclopropanecarboxamido)-3-ethylpyridin-2-yl)benzoate which was used without further purification.
