Reaction Steps

To a flask containing 2-methyl-2-(methylsulfonyl)-N-(tetrahydro-2H-pyran-2-yloxy)-4-[4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]butanamide prepared as in Preparation Number 3 (150 mg, 0.312 mmol) was added 2-iodophenol (89.3 mg, 0.406 mmol), cesium fluoride (190 mg, 1.25 mmol), water (500 uL) and 1,4-dioxane (3 mL). To this mixture was added Palladium tetrakis (54.3 mg, 0.047 mmol) and the mixture was heated to 115° C. with stirring overnight. The mixture was diluted with ethyl acetate and water. The phases were separated and the crude organic extract was concentrated in vacuo to dryness. The crude material was purified via silica gel chromatography eluting with ethyl acetate/heptanes to afford 4-(2′-hydroxybiphenyl-4-yl)-2-methyl-2-(methylsulfonyl)-N-(tetrahydro-2H-pyran-2-yloxy)butanamide as solid. 19.6 mg LCMS: (M−1) 446.3.
