反应详情

A mixture of 2,4-dichlorophenol (1.2 g, 7.6 mmol) and potassium carbonate (2.1 g, 15.2 mmol) is stirred together in dimethylsulfoxide (20 ml). N-methylcarbonyl 2-nitro-5-fluoroaniline (1.5 g, 7.6 mmol) is added in portions. After 1 hour, the reaction is heated to 100° for 1.5 hours. The reaction is then cooled to RT and diluted with water. A solid is collected, dissolved in chloroform, washed with water, dried and stripped to give N-methylcarbonyl 2-nitro-5-(2,4-dichlorophenoxy)aniline.
