実験手順
84 g of 2-methyl-3-nitroaniline is dissolved in 550 ml of THF. 53 ml of acetic anhydride is slowly added dropwise and the mixture is then stirred at 70° C. After about 1 hour, THF is distilled off and the residue is combined with 250 ml of petroleum ether. The solid precipitate is filtered off and dried at 50° C. 106 g of N-acetyl-2-methyl-3-nitroaniline is obtained as a light brown powder.
