Versuchsvorschrift

A solution of the 2,3-dimethyl-indolizine-8-carboxylic acid methyl ester (265 mg, 1.3 mmol) in ether (10 ml) was cooled to 0° C. and treated with LAH (1.0M in THF, 1.6 ml, 1.6 mmol, dropwise addition). After 3.5 h the reaction was quenched with sodium sulfate decahydrate (added in small portions until gas evolution ceased). The resulting mixture was stirred for 0.5 h and the precipitated solids were removed via filtration and washed with EtOAc. The combined filtrates were concentrated to give the product which was used without further purification.
