Reaktionsschritte

To a solution of (2-(1-methoxycycloheptyl)-5-(trifluoromethyl)benzyloxy)triisopropylsilane (276 mg; 0.602 mmol) in tetrahydrofuran (3.5 mL) was added tetrabutylammonium fluoride (0.62 mL; 0.62 mmol; 1.0 M solution in tetrahydrofuran). Reaction was stirred at room temperature for 1.5 hours. Solvent was evaporated under reduced pressure. The residue was purified by 12 g RediSep column (Teledyne Isco Inc., Lincoln Nebr.) (eluted with 10-30% ethyl acetate in heptane) to yield 169 mg (92.9%) of the title compound as a colorless gum.
