Versuchsvorschrift
To the solution of 2.19 g (8.75 mmol) 3-nitro-5-(2-oxo-pyrrolidin-1-yl)-benzoic acid in 50 ml MeOH/THF 3/2 are added 0.2 g Pd/C (10% Engelhard 4505) and the reaction is stirred at rt under hydrogen (1 atm) for 18 h. After filtration through celite the solvent is evaporated at reduced pressure to give the product.
