실험 절차

To a solution of 100 mg (0.26 mmol) of 2-(1-benzyl-2-methyl-1H-indol-5-yl)-1,1,1,3,3,3-hexafluoro-propan-2-ol (example 80) in 1 mL of acetonitrile were added 25 mg (0.185 mmol) of NCS. After stirring at RT for 2 hrs, the mixture was 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. Column chromatography on silica gel with n-heptane/CH2Cl2 1:3 yielded 70 mg (65%) of 2-(1-benzyl-3-chloro-2-methyl-1H-indol-5-yl)-1,1,1,3,3,3-hexafluoro-propan-2-ol, white solid, MS: 420 ((M−H−), 1Cl).
