Reaction Steps
To 150 ml of a nitromethane solution of 17.33 g (72.1 mmol) of ethyl 3-[(1R,2S)-2-t-butoxycarbonylcyclopropyl)acrylate was added 14.47 ml (115.4 mmol) of tetramethylguanidine at room temperature, and the mixture was stirred at 70° C. for 3.5 hours. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography (hexane:ethyl acetate=85:15) to give 18.95 g (87.2%) of the title compound as a colorless oily substance.
