Procedure

The appropriate 2-nitrobenzoic acid was initially reacted analogously to general methods 2 and 5 with the respective amine to give a 2-nitrobenzamide. Then 4 mmol of the 2-nitrobenzamide were hydrogenated in 50 ml of THF and 50 ml of methanol in the presence of a spatula tip of 10% palladium on carbon at RT under atmospheric pressure. The catalyst was filtered off with suction, the reaction mixture is concentrated, and the corresponding 2-aminobenzamide was obtained.
