Procedure

A solution of 400 mg (1.07 mmol) of 2-(1-benzyl-1H-indol-5-yl)-1,1,1,3,3,3-hexafluoro-propan-2-ol (example 16) in 2 mL CH2Cl2 was treated portionwise with 286 mg (2.14 mmol) of NCS and stirred at RT for 10 hrs. Evaporation of the solvent and column chromatography on silica gel with n-heptane/EtOAc 3:1 to 1:1 yielded 100 mg (21%) of 2-(1-benzyl-2,3-dichloro-1H-indol-5-yl)-1,1,1,3,3,3-hexafluoro-propan-2-ol, light brown oil, MS: 441 (M−H)−, 2Cl.
