Participants

Reaction Steps

A similar procedure as described in Example 12, step 8 was used, starting from 4-{3-[6-(3-iodo-5-thiophen-3-yl-phenoxy)-hexyl]-2-(2-ethoxycarbonyl-ethyl)-phenoxy}-butyric acid ethyl ester (216 mg, 0.31 mmol) and phenylboronic acid (152 mg, 1.25 mmol) to give 4-{2-(2-ethoxycarbonyl-ethyl)-3-[6-(5-thiophen-3-yl-biphenyl-3-yloxy)-hexyl]-phenoxy}-butyric acid ethyl ester (110 mg, 55%) as a colorless oil: ES(+)-HRMS m/e calculated for C39H46O6S (M+Na)+ 665.2907, found 665.2907.
