Reaction Steps
A solution of N-(4-nitro-phenyl)-oxalamic acid ethyl ester (4.9 g, 20.5 mmol), triethylamine (4.2 g, 41 mmol) and 2-amino-4,6-dimethylpyridine (2.5 g, 20.5 mmol) in dry toluene (30 mL) was heated at reflux overnight. The mixture was cooled to 0° C., and a precipitate was filtered and washed with water. Drying under vacuum afforded N-(4,6-dimethyl-pyridin-2-yl)-N′-(4-nitro-phenyl)-oxalamide (4.8 g, 74%).
