Procedure

N-(6-chloro-5-methylpyridin-2-yl)-1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)cyclopropanecarboxamide (325.2 mg, 0.89 mmol), 2-(2-oxo-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-1(2H)-yl)acetonitrile (0.300 g, 1.15 mmol), tetrakis(triphenylphosphine)palladium (0) (51 mg, 0.044 mmol) and potassium carbonate (1.71 g, 1.11 mL of 2 M, 2.21 mmol) were combined in a scintillation vial containing 1,2-dimethoxyethane (8 mL). The reaction mixture was then stirred and heated to 80° C. overnight. The crude reaction mixture was purified by reverse-phase preparative liquid chromatography to yield the product (25.3 mg, 6.1%) as a trifluoracetic acid salt. ESI-MS m/z calc. 464.1. found 465.1 (M+1)+. Retention time 2.00 minutes.
