Participants

Reaction Steps

5-{6-[2-(2-Ethoxycarbonyl-ethyl)-3-(3-ethoxycarbonyl-propoxy)-phenyl]-hexyloxy}-3′-fluoro-biphenyl-3-carboxylic acid tert-butyl ester (7.0 g) was dissolved in a mixture of TFA and dichloromethane (1:1, 80 mL) and stirred at room temperature for 1 h. The solvents were removed under reduced pressure and the crude material was purified on a silica gel column using ethyl acetate and hexanes to yield the title compound (5.9 g, 90% yield).
