Reaction Steps

A solution of N-{5-cyano-2-[4-hydroxy-6-(5-methanesulfonyl-2,3-dihydrobenzofuran-7-yl)-6-methyl-4-trifluoromethylhept-1-ynyl]-3-methylphenyl}-2,2,2-trifluoroacetamide (154 mg, 0.25 mmol) in 0.6 mL of anhydrous DMSO was heated in the presence of 1,1,3,3-tetramethylguanidine (0.094 mL, 0.75 mmol) in a microwave at 140° C. for 10 minutes. The reaction was quenched with a mixture of 1 N sulfuric acid and 10 mL of crushed ice. The resulting precipitate was filtered, washed with water, and dried. Preparative TLC chromatography (50% ethyl acetate in hexanes, followed by 15% ethyl acetate in dichloromethane) gave 23 mg of the title product as an off-white solid (18% yield).
