실험 절차

A solution of cyclohex-2-en-1-ol (10.0 g, 101.9 mmol) in anhydrous THF (100 mL) was added to a stirred suspension containing sodium hydride (8.0 g, 199.7 mmol) (60% dispersion in oil) and benzyl bromide in anhydrous THF (250 mL) maintained at 50° C. The resulting solution was stirred at 55-60° C. for 18 h. After cooling to ambient temperature, water was added to quench the reaction and the mixture was diluted with ether (500 mL). The organic phase was separated, dried (Na2SO4), filtered and concentrated in vacuo to an oil that was subjected to a short silica plug filtration to provide 16.1 g of desired product 51a that was used directly in the next step without further purification.
