実験手順

850 mg 1-[4-Butyl-2-(4-trifluoromethyl-phenyl)-thiazol-5-ylmethyl]-5-methoxy-1H-pyrrolo[2,3- b]pyridine was dissolved in 50 ml dichloromethane. At −78° C. 1.90 ml of a 1 molar solution of borontribromide in dichloromethane was added. The reaction mixture was allowed to warm up to room temperature. Then the reaction mixture was heated under reflux for additional two hours. 150 ml ethyl acetate were added and the mixture washed with 50 ml of a one molar solution of hydrochloric acid. The organic layer was dried over MgSO4 and the solvent removed under reduced pressure. The residue was purified by RP-HPLC to provide 930 mg 1-[4-Butyl-2-(4-trifluoromethylphenyl)-thiazol-5-ylmethyl]-1H-pyrrolo[2,3-b]pyridin-5-ol as a lyophilisate.
