m -nitrocumene as only a minor component of the nitration product. However, the conversion of 4-isopropyl-2-nitroaniline to m -isopropylnitrobenzene, which was used to illustrate reductive deamination of arylamines in the text, establishes the last step in the synthesis. Our task simpli f es itself to the preparation of 4-isopropyl-2-nitroaniline from cumene. The follow- ing procedure is a straightforward extension of the reactions and principles developed in this chapter. Reductive deamination of 4-isopropyl-2-nitroaniline by diazotization in the presence of ethanol or hypophosphorous acid yields m -nitrocumene and completes the synthesis. 22.21 Amines may be primary, secondary, or tertiary. The C 4 H 11 N primary amines, compounds of the type C 4 H 9 NH 2 , and their systematic names are
