Versuchsvorschrift

To a solution of 2-Bromo-6-(4-tert-butyl-cyclohexyloxy)-naphthalene (2 g, 0.006 mol) in 15 mL dry THF stirring at −78° C., was added dropwise. The reaction was then stirred at −78° C. for 15 minutes, yellow color results. 2,2,2-Trifluoro-N-methoxy-N-methyl-acetamide (1.0 mL, 0.0083 mol) in 10 mL THF was then added dropwise while the reaction was stirred at −78° C. Once all of the starting material was added reaction the reaction was allowed to warm to room temperature while stirring for 2 hours. The Reaction was then quenched with water and extracted three times with EtOAc. Organics were dried over MgSO4, filtered, and concentrated to dryness under reduced pressure. Crude NMR shows about 80% purity (looks like des-bromostarting material). Material was purified via column chromatography using a gradient of hexanes for one column volume followed by 0-10% EtOAC/Hexanes on 25 g of SiO2 to give the title compound as a yellow solid. Material will be carried on without additional purification
