Reaction Steps

To {3-[4-(2,2-dimethyl-propionylamino)-2-(2,2,2-trifluoro-ethylsulfanylmethyl)-phenoxy]-4-methoxy-phenyl}-acetic acid (0.128 g, 0.26 mmol) in MeCN (3 mL) was added iodomethane (0.03 mL, 0.53 mmol), followed by sodium hydride (60% in mineral oil; 0.021 g, 0.53 mmol). The reaction was stirred at room temperature, but only starting material was seen by analytical LCMS, so the reaction was heated to 60° C. for 2 hours, and then cooled to room temperature and stirred for 2 days under N2. The mixture was used directly in the hydrolysis step. To a solution of {3-[4-[(2,2-dimethyl-propionyl)-methyl-amino]-2-(2,2,2-trifluoro-ethylsulfanylmethyl)-phenoxy]-4-methoxy-phenyl}-acetic acid methyl ester (0.26 mmol) in MeCN was added H2O, MeOH, and lithium hydroxide, and the reaction was heated to 65° C. for 1 hour to give the title compound.
