Versuchsvorschrift

4-(1-(4-Methoxyphenyl)-3-(methylthio)-1H-indol-2-yl)-3,5-dimethylisoxazole (the intermediate product of step (c) from the synthesis of Example 21, 140 mg, 0.38 mmol) and 2-mercaptobenzoic acid (118 mg, 0.77 mmol) were added to 5 ml of trifluoroacetic acid at RT. The mixture was stirred as a slurry at RT under an atmosphere of nitrogen over night. 2M NaOH and EtAc were added and the phases were separated. The solvents were evaporated and the residue was purified by flash chromatography with heptane/EtAc 4:1 as eluent to provide 4-(1-(4-methoxyphenyl)-1H-indol-2-yl)-3,5-dimethylisoxazole in 86% yield. ES/MS m/z: 319.1 (M+H)
