반응 단계

Next is the mixing of one part 4-tert-butylanisole with between substantially 0-9 parts (by volume) organic solvent such as ethylene dichloride. Next is the cooling of the reaction mixture of 4-tert-butylamine and organic solvent to a temperature below 5° C. This is followed by the adding of 70% concentrated nitric acid while maintaining the temperature of the reaction mixture below 10° C. to produce 2-nitro-4-tertbutylanisole and a 4-nitroanisole byproduct. These are separated by means of vacuum distillation. Specifically, the 4-nitroanisole byproduct has a boiling point of 86° C. while the desired 2-nitro-4-tertbutylanisole has a boiling point of 102°-105° C. at a pressure of 1 mmHg.
