実験手順
A solution of methyl (1-benzylpyrrolidin-3-ylidene)acetate a45 (3 g, 1.2 mmol, 1 eq), 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU, 0.7 g, 4.6 mmol, 3.8 eq) in nitromethane (30 ml) is refluxed for 30 h. The solution is concentrated in vacuum and the resulting oil is purified by chromatography over silicagel (ethyl acetate/hexane 30/70) to afford 3.7 g of methyl [1-benzyl-3-(nitromethyl)pyrrolidin-3-yl]acetate a46 as a black oil.
