Reaction Steps

A mixture of 4-methyl-3-nitrobenzoic acid (1.97 g) and thionyl chloride (6 mL) was heated under reflux for 18 hours. The reaction liquid was concentrated under reduced pressure, followed by an azeotropic process with toluene to give a red-brown oil. To a mixture of the red-brown oil and THF (25 mL), diethylamine (2.6 mL) was added under ice cooling and stirred at room temperature for 5 hours. The reaction liquid was poured into water and extracted with ethyl acetate. The organic layer was washed with saturated aqueous sodium chloride and then dried over anhydrous sodium sulfate, and the solvent was distilled off under reduced pressure to give N,N-diethyl-4-methyl-3-nitrobenzamide (2.61 g) as a brown oil.
