Versuchsvorschrift

Methyl 2-methyl-3-(3-pyridyl)-5,6,7,8-tetrahydroindolizine-1-carboxylate is prepared as in Example 1, from 2.56 g of the sodium salt of N-nicotinoylpiperidine-2-carboxylic acid and 7.16 g of 2-bromo-2-methylbutenoate. 1.2 g of methyl 2-methyl-3-(3-pyridyl)-5,6,7,8-tetrahydroindolizine-1-carboxylate are thus obtained in the form of an orange oil (Rf=0.25; thin layer chromatography on silica gel; eluent: 8/2 dichloromethane/ethyl acetate).
