Versuchsvorschrift

Cyclopropane-1,1-dicarboxylic acid (10 g) in acetonitrile(200 ml) was treated with triethylamine (43 ml) and iodomethane (19 ml) at room temperature. The solution was stirred for 2 h then heated at 75° C. for 16 h. The solvent was removed under reduced pressure, the residue dissolved in water, extracted with ethyl acetate, dried(MgSO4) and evaporated to a brown oil (6.70 g).
