実験手順
A mixture of N,N,5-trimethyl-2-nitrobenzamide (11 g, 52.8 mmol) and 5% palladium on carbon (1 g) in 100 mL of ethanol was stirred under a hydrogen atmosphere for 18 hours. Additional 5% palladium on carbon (1 g) was added and the mixture was stirred for approximately 8 hours. The mixture was filtered and the filtrate was concentrated. The residue was purified on silica gel by flash chromatography eluting with 4% ethanol/methylene chloride to give 2-amino-N,N,5-trimethylbenzamide (8 g, 44.9 mmol), m.p. 98°-99° C.
