10% Palladium on carbon (100 mg) is added to a solution of N,3,5-trimethyl-4-nitrobenzamide (1 g) in methanol (10 mL) and the mixture is hydrogenated for 3 hours under 3 bar hydrogen pressure. Then the catalyst is filtered off and washed with methanol. The combined mother liquors are concentrated to give the title compound. Yield: 850 mg; LC (method 21): tR=6.02; Mass spectrum (ESI+): m/z=179 [M+H]+.
