Reaction Steps
3-Amino-4-ethylamino-benzoic acid methyl ester (6.4 g) was prepared by following General Procedure B starting from 4-ethylamino-3-nitro-benzoic acid methyl ester (8.3 g) and Pd/C (20% by weight, 170 mg) in MeOH:EtOAc (1:1, 50.0 mL). The crude product was used in the next step without further purification.
