N,N,3,5-Tetramethyl-4-nitrobenzamide → 4-amino-N,N,3,5-tetramethylbenzamide

Participants

Reaction Steps

10% Palladium on carbon (100 mg) is added to a solution of N,N,3,5-tetramethyl-4-nitrobenzamide (1 g) in methanol (10 mL) and the mixture is hydrogenated for 3 hours under 2 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: 1 g; LC (method 20): tR=2.75 min; Mass spectrum (ESI+): m/z=193 [M+H]+.
