Procedure

To 60 ml of a nitromethane solution of 6.07 g (25.2 mmol) of ethyl 3-(cis-2-t-butoxycarbonylcyclopropyl)acrylate was added 3.48 ml (27.7 mmol) of tetramethylguanidine at room temperature, and the mixture was stirred for 6 hours. To the reaction mixture was further added 0.32 ml (2.52 mmol) of tetramethylguanidine, followed by stirring for 18 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 6.536 g (85.9%) of the title compound as a pale yellow oily substance.
