A 250 ml, 3-necked round bottomed flask is equipped with a magnetic stirrer. The reaction is conducted under a positive nitrogen pressure, maintained with an oil filled bubbler. The reaction vessel is charged with dimethyloxosulfonium methylide (36 ml of 0.932M solution, 0.034 moles) in dimethyl sulfoxide. 4-(5-Methoxyheptyl)bicyclo[3.2.0]heptan-6-one (7.7 g, 0.032 moles) is added neat to the stirring solution by a syringe. The reaction vessel is heated in a 40° C. water bath for 60 minutes and then a sample is removed and analyzed by infra-red spectroscopy.
