Versuchsvorschrift

To a solution of 19 mg (0.036 mmol) of 2-[2-methyl-5-(2,2,2-trifluoro-1-triethylsilanyloxy-1-trifluoromethyl-ethyl)-2,3-dihydro-indol-1-yl]-2-phenyl-ethanol in 0.5 mL THF were added 0.043 mL (0.043 mmol) of a 1M TBAF solution in THF. After stirring at RT for 24 hrs the mixture was distributed between Et2O and a saturated aqueous solution of NH4Cl. The combined organic phases were dried over Na2SO4 and evaporated. Column chromatography on silica gel with n-heptane/EtOAc 2:1 yielded 9.3 mg (62%) of 1,1,1,3,3,3-hexafluoro-2-[1-(2-hydroxy-1-phenyl-ethyl)-2-methyl-2,3-dihydro-1H-indol-5-yl]-propan-2-ol, yellow viscous oil, MS: 420 (MH+).
