1i (261 mg, 0.6 mmol) and 4-(6-Fluoro-pyridin-2-yl)-tetrahydro-pyran-4-carbonitrile (1j, 123 mg, 0.6 mmol) were dissolved in DMF and degassed with N2 for 10 minutes. Potassium tert-butoxide (81 mg, 0.72 μmmol) was added, and the mixture was degassed with N2 for an additional 10 minutes. The reaction was heated to 90° C. for 24 hours, then cooled to room temperature. The solution was diluted with EtOAc and water, and the aqueous layer was extracted with EtOAc. The combined organic layers were dried over MgSO4, filtered, and concentrated, and the residue was purified by silica gel chromatography to obtain the desired product, 1k.
