Reaction Steps

In accordance with a more specific aspect of the present invention, a process is provided for producing N-sec-butyl-4-tert-butyl-2,6-dinitroaniline. The process may be broadly described as: (1) reacting 4-tert-butylphenol with dimethyl sulfate to produce 4-tert-butylanisole (a methylation reaction); (2) reacting the 4-tert-butylanisole with nitric acid, a reacting the 4-tert-butylanisole with nitric acid, a mixture of nitric acid and sulfuric acid or a mixture of nitric acid, sulfuric acid and oleum to produce 2,6-dinitro-4-tert-butylanisole (a nitration reaction); and (3) reacting the 2,6-dinitro-4-tert-butylanisole with sec-butylamine to produce N-sec-butyl-4-tert-butyl-2,6-dinitroaniline (an amination reaction).
