Reaction Steps

To flask containing 2-methanesulfonyl-2-methyl-N-(tetrahydro-pyran-2-yloxy)-4-[4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-butyramide which may be prepared by the method described in Preparation 3 (800 mg, 01.66 mmol) was added cyclohept-1-en-1-yl trifluoromethanesulfonate (812 mg, 3.32 mmol), sodium carbonate (528 mg, 4.99 mmol), water (500 uL) and 1,4-dioxane (4 mL). To this mixture was added pd tetrakis (288 mg, 0.249 mmol) and the mixture was heated to 50° C. with stirring overnight. The mixture was diluted with ethyl acetate and washed with water 2×. The phases were separated, silica gel was added to the organic extracts and the mixture was concentrated to dryness. The crude material was purified via silica gel chromatography eluting with ethyl acetate/heptanes to afford 4-(4-cyclohept-1-en-1-ylphenyl)-N-[(1-methoxypentyl)oxy]-2-methyl-2-(methylsulfonyl)butanamide as a solid 205 mg. LCMS: (M+1) 448.3.
