PROCEDURE

实验过程

A mixture of 2-carboxymethyl-1-(4-isopropoxyphenyl)-5-(5-trifluoromethyl-2-pyridinyloxy)indole-3-carboxylic acid (85 mg, 0.16 mmol, see Example 26), EtOH (0.8 mL) and HCl (1 M in EtOH, 0.1 mL) was heated at reflux for 20 min, concentrated, diluted with water, neutralized with NaHCO3 (aq, sat) and extracted with EtOAc. The organic layer was washed with brine, dried (Na2SO4), concentrated and purified by chromatography to give the title compound. Yield 45 mg (52%), mp 202° C.
