実験手順

To a solution of 3-bromo-5-{6-[2-(2-ethoxycarbonyl-ethyl)-3-(3-ethoxycarbonyl-propoxy)-phenyl]-hexyloxy}-benzoic acid tert-butyl ester (2.3 g, 3.46 mmol) in dichloromethane (25 mL) was added trifluoroacetic acid (10 mL) at room temperature. The resulting light brown solution was stirred for 4 h. Then, the dichloromethane and excess TFA was removed under reduced pressure and the residue was dissolved in toluene and again removed under reduced pressure to remove all TFA to obtain 3-bromo-5-{6-[2-(2-ethoxycarbonyl-ethyl)-3-(3-ethoxycarbonyl-propoxy)-phenyl]-hexyloxy}-benzoic acid (2.1 g, 100%) as a light brown oil.
