Reaction Conditions

Reaction Steps

A mixture of 10.4 g of 5-tert-amylsalicylic acid and 7.6 g of 2-methyl-4-nitroaniline in 100 ml of xylene is heated at 70° C and to the mixture is added a solution of 2.6 g of phosphorus trichloride in 10 ml of xylene. The whole mixture is refluxed for two and a half hours. The hot reaction solution is decanted. The supernatant solution is cooled on an ice bath. The crystalline precipitate is collected by filtration. Recrystallization from methanol gives 9.4 g of the title compound as pale yellow crystals, melting at 150°-151° C.
