Reaction Conditions:

with sulfuric acid;HNO₃ at 10 - 50; for 1 h;Temperature;

Steps:

1; 5-6

Slowly add 1 mol of N-methylphthalimide prepared above into a reactor containing concentrated sulfuric acid and concentrated nitric acid at a molar ratio of 3:1, and control the temperature below 10°C. After the addition is complete, the water bath is heated to 50 Incubate at for 1h, extract, filter, wash, and dry to obtain a sample. The sample obtained after testing is N-methyl-4nitro-phthalimide, with a yield of 97% and a purity of 99%.
