A solution of 100 mg (0.29 mmol) of 1,1,1,3,3,3-hexafluoro-2-[4-(2,2,2-trifluoro-ethylamino)-phenyl]-propan-2-ol (example 11.2) in 0.5 mL tBuOH was treated with 115 mg (0.44 mmol) of 5-chloro-2-chloromethyl-benzo[b]thiophene and stirred at 120° C. for 10 hours in a sealed tube. Evaporation of the solvent and column chromatography on silicagel with n-heptane/EtOAc 8:1 yielded 30 mg (19%) of 2-{4-[(5-chloro-benzo[b]thiophen-2-ylmethyl)-(2,2,2-trifluoro-ethyl)-amino]-phenyl}-1,1,1,3,3,3-hexafluoro-propan-2-ol, light yellow oil, MS: 520 ((M-H)−, 1Cl).
