Reaction Steps
An alternative synthesis for N-sec-butyl-4-tert-butyl-2,6-dinitroaniline is set forth in U.S. Pat. Nos. 4,289,907 and 4,395,572 to Chan. The starting material in this synthesis is a nitrophenol such as 2,6-dinitro-4-tert-butylphenol. The nitrophenol is methylated by reaction with methyl iodide/potassium carbonate to produce 4-tert-butyl-2,6-dinitroanisole. The 4-tert-butyl-2,6-dinitroanisole is then reacted with sec-butylamine to produce N-sec-butyl-4-tert-butyl-2,6-dinitroaniline. While effective in producing the desired product, this process also suffers from a number of distinct disadvantages.
