Reaction Steps

5m (93 mg, 0.2 mmol) and 4-(6-Fluoro-pyridin-2-yl)-tetrahydro-pyran-4-carbonitrile (5n, 41 mg, 0.2 mmol) were dissolved in DMF (2 mL) and degassed with N2. Potassium tert-butoxide (22 mg, 0.2 mmol) was added, and the reaction was sealed and heated to 80° C. overnight. After cooling to room temperature, the mixture was diluted with EtOAc and water, and the aqueous phase 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, 5p.
