Procedure

To a solution of 4-{2-(2-ethoxycarbonyl-ethyl)-3-[6-(5-hydroxymethyl-4′-methanesulfonyl-biphenyl-3-yloxy)-hexyl]-phenoxy}-butyric acid ethyl ester (250 mg, 0.37 mmol) in DMF (5 mL) were added sodium hydride (29.9 mg, 0.75 mmol), and iodomethane (106.2 mg, 0.75 mmol) at room temperature. The resulting suspension was stirred for 15 h and then the excess sodium hydride was quenched by slow addition of water (5 mL). The mixture was diluted with 1.0N hydrochloric acid (25 mL) and the organic compound was extracted into ethyl acetate (2×25 mL). The combined extracts were washed with brine solution (50 mL) and dried over anhydrous magnesium sulfate. Filtration of the drying agent and removal of the solvent under vacuum afforded the crude residue which was purified by using an ISCO 40 g column to obtain 4-{2-(2-ethoxycarbonyl-ethyl)-3-[6-(4′-methanesulfonyl-5-methoxymethyl-biphenyl-3-yloxy)-hexyl]-phenoxy}-butyric acid ethyl ester (200 mg, 78%) as a light brown oil: ES(+)-HRMS m/e calcd for C38H50O9S (M+Na)+ 705.3068. found 705.3069.
