Procedure

To a solution of 400 mg of 3-{4-[4-hydroxymethyl-2-(4-trifluoromethyl-phenyl)-thiazol-5-ylmethoxy]-2-methoxy-phenyl}-4H-[1,2,4]oxadiazol-5-one in 8 mL of dimethylformamide was added 0.42 mL of triethylamine followed by dropwise addition of 0.1 mL of methanesulfonyl chloride. The resulting mixture was stirred at room temperature for 45 minutes then concentrated under reduced pressure to give 830 mg of crude methanesulfonic acid 5-[3-methoxy-4-(5-oxo-4,5-dihydro-[1,2,4]oxadiazol-3-yl)-phenoxymethyl]-2-(4-trifluoromethyl-phenyl)-thiazol-4-ylmethyl ester which was used in the next step without further purification.
