Procedure
To 3-[(6-(3-cyanophenoxy)-3,5-difluoro-4-methylpyridin-2-yl)oxy]benzene-propionic acid (0.50 g, 1.2 mmol) in methylene chloride (20 mL) was added methyl iodide (0.26 g, 1.8 mmol) and diazabicycloundecane (2.8 g, 1.8 mmol). After stirring for 15 hours, the solution was concentrated in vacuo and chromatographed on silica gel with ethyl acetate/hexane (1/4) to give 3-[(6-(3-cyanophenoxy)-3,5-difluoro-4-methylpyridin-2-yl)oxy]benzenepropionic acid, methyl ester; NMR (CDCl3) 7.3 (m,5), 7.05 (d,1), 6.85 (m,2), 3.68 (s,3), 2.9 (t,2), 2.55 (t,2), 2.4 (s,3) ppm.
