Versuchsvorschrift

Triethylamine (0.10 mL, 0.72 mmol), t-butyldimethylsilyl chloride (48.5 mg, 0.322 mmol) and dimethylaminopyridine (1 mg, 0.008 mmol) were added to a solution of (E)-4-(4-{1-ethyl-1-[3-methyl-4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-propyl}-2-methyl-phenyl)-1,1,1-trifluoro-2-trifluoromethyl-3-buten-2-ol (Example 26-(5); 47.0 mg, 0.082 mmol) in N,N-dimethylformamide (0.10 mL), and the mixture was stirred at room temperature for 24 hours. Water was added to the reaction mixture, followed by extraction with diethyl ether. The extract was dried over anhydrous magnesium sulfate and then concentrated under reduced pressure. The residue was purified by silica gel chromatography (hexane/ethyl acetate=50/1) to give the title compound (47 mg, 84%).
