Reaction Steps

22 mg (0.082 mmol) (3-phenylethynyl-cyclohex-3-enyl)-carbamic acid ethyl ester are dissolved in 2 ml DMF and 1 mL THF. 8 mg (0.165 mmol) of a 60% dispersion of NaH in oil is added and the mixture stirred under argon for 90 minutes at room temperature. The reaction mixture is cooled to 0°, and 16 microliters Mel in 0.5 ml THF are added dropwise. After stirring one hour at room tenmperature, the reaction mixture is cooled to 0° again, ice is added and the crude product extracted with ethyl acetate, washed with water and saline, dried with sodium sulfate and column chromatographed using a 4:1 mixture of petroleum ether and ethyl acetate.
