Reaction Steps

A mixture of 13 parts of 3-[1-(ethoxycarbonyl)-3-pyrrolidinyl]-2-propenoic acid and 100 parts of acetic acid was hydrogenated at normal pressure and at 20° C. with 2 parts of palladium-on-charcoal catalyst 10%. After the calculated amount of hydrogen was taken up, the catalyst was filtered off and the filtrate was evaporated. The residue was taken up in methylbenzene and the latter was evaporated again, yielding 13 parts (100%) of 1-(ethoxycarbonyl) -3-pyrrolidinepropanoic acid as a residue (int. 28).
