実験手順

To a solution of 0.93 g (1.66 mmol) of 2-(1-benzyl-2-triisopropylsilanyloxymethyl-1H-indol-5-yl)-1,1,1,3,3,3-hexafluoro-propan-2-ol in 10 mL of THF were added 1.66 mL (1.66 mmol) of a 1 M solution of tetrabutyl ammonium fluoride in THF. The mixture was stirred at RT for 1 h and poured into a mixture of a saturated aqueous solution of NH4Cl and Et2O. The phases were separated and the aqueous one was extracted with Et2O. The combined organic phases were dried over Na2SO4 and evaporated to yield 1.0 g (quantitative) of 2-(1-benzyl-2-hydroxymethyl-1H-indol-5-yl)-1,1,1,3,3,3-hexafluoro-propan-2-ol, light yellow semisolid, MS: 402 (M−H)−.
