Procedure
A similar procedure as described in Example 4, step 5 was used, starting from 4-[3-[6-(5-acetyl-biphenyl-3-yloxy)-hexyl]-2-(2-ethoxycarbonyl-ethyl)-phenoxy]-butyric acid ethyl ester (282 mg, 0.47 mmol) and 1.0 N aqueous sodium hydroxide (10 mL) to afford 4-[3-[6-(5-acetyl-biphenyl-3-yloxy)-hexyl]-2-(2-carboxy-ethyl)-phenoxy]-butyric acid (168 mg, 66%) as a white solid: ES(+)-HRMS m/e calcd for C33H38O7 (M+Na)+ 569.2510. found 569.2508.
