Versuchsvorschrift

A solution of 11.0 g (44.0 mmol) of 3-hydroxy-4-ethyloxycarbonyl-1-phenylmethyl pyrrolidine (prepared according to E. Jaeger and J. H. Biel in J. Org. Chem. 1965, 30, (740) in 40 g of 25% ammonia in methanol was heated at 100° C. under pressure overnight. The solution was cooled and evaporated to dryness. The oily residue was purified by chromatography using dichloromethane-methanol (85:15) to yield 2.14 g (22%) of the title compound. M.P. 128° C.
