실험 절차

Lithium hydroxide (1M aqueous solution, 0.45 ml) was added to a solution of ethyl 6-(benzenesulphonylmethyl)-2-methoxy-3-propylbenzoate (Intermediate 24, 0.034 g) in dioxane and the solution was stirred and heated in the microwave at 160° C. for 15 minutes. The cooled solution was acidified by addition of formic acid and then purified by preparative HPLC (C18) eluting with a mixture of methanol and water containing 0.1% formic acid to give 6-(benzenesulphonylmethyl)-2-methoxy-3-propylbenzoic acid (0.024 g) as a white solid.
