Reaction Steps

To a solution of {6-[2-methyl-6-(4-trifluoromethyl-phenyl)-pyridin-3-ylmethoxy]-indol-1-yl}-acetic acid tert-butyl ester (20 mg, 0.04 4 μmol) in THF/methanol 2/1 (3 ml) was added a 1 N aqueous LiOH solution (1 ml). The reaction mixture was stirred for 14 h at ambient temperature, neutralized with 1 N aqueous HCl solution under ice cooling and concentrated under reduced pressure. The residue was dissolved in 1 N HCl/ice water 1/1 and ethyl acetate, the layers were separated and the aqueous layer was extracted with ethyl acetate. The combined organic layers were washed with ice water/brine 1/1, dried over sodium sulfate and the solvent was evaporated in vacuo to give the title compound (18 mg, 0.04 μmol, quant.) as white solid.
