A similar procedure as described in Example 40, step 8 was used, starting from 4-[3-[6-(3-benzothiazol-5-yl-5-methanesulfonyl-phenoxy)-hexyl]-2-(2-ethoxycarbonyl-ethyl)-phenoxy]-butyric acid ethyl ester (100 mg, 0.14 mmol) and 1.0 N aqueous sodium hydroxide (1.44 mL) to afford 4-[3-[6-(3-benzothiazol-5-yl-5-methanesulfonyl-phenoxy)-hexyl]-2-(2-carboxy-ethyl)-phenoxy]-butyric acid (50 mg, 54.4%) as an amorphous white solid: ES(+)-HRMS m/e calcd for C33H37NO8S2 (M+H)+ 640.2034, found 640.2030.
