Versuchsvorschrift
To a solution of 4-(2-chloroethylamino)-3-nitro-benzoic acid methyl ester (12.7 g, 0.0492 mol) in methanol (500 mL) was added 10% Pd/C (1.3 g) under a N2 atmosphere. The reaction mixture was hydrogenated in a Parr apparatus at 3 kg pressure for 2 h. The catalyst was filtered over celite and the filtrate was concentrated affording 11.0 g (98%) of 3-amino-4-(2-chloroethylamino)-benzoic acid methyl ester as a solid.
