実験手順

To 2-chloro-5-nitroaniline (2 g, 11.59 mmol) in pyridine (5 mL) at room temperature was added 4-methylbenzoyl chloride (1.6 mL, 12.17 mmol), followed by pyridine (5 mL). The mixture was then stirred at room temperature for 16 h. Ethyl acetate was then added to the solution to give a precipitate, which was filtered off and washed twice with ethyl acetate, and then hexanes. The resulting solid was then washed with aqueous sodium bicarbonate, 1M aqueous sodium hydroxide, water and hexanes to afford (1.4 g, 42%) of the title compound.
