Versuchsvorschrift

To a flame dried flask under nitrogen was charged 84 mg (2.10 mmol) of 60% sodium hydride in mineral oil and 3.0 mL of THF and the mixture cooled to 0° C. Cyclohexanol (0.18 mL/1.70 mmol) was added and the reaction mixture stirred for 5 min. A solution of 102 mg (0.419 mmol) of the product from Method L in 1.0 mL of THF was added and the mixture heated to reflux for 3 h. After cooling to room temperature, the reaction mixture was acidified to pH 1 with 2 N HCl and concentrated in vacuo. The resulting residue was then slurried in ethyl acetate, filtered and the filtrate concentrated in vacuo to provide 76 mg (59%) of the title compound as an oil. LRMS: 308 (M+1).
