In some more complex cases, secondary amines can be nitrated directly with nitrating mixtures.
oxygen-function carboxylic acid[halogenated, sulphonated, nitrated or nitrosated derivatives (or any combination of such derivatives)]
Phenols and anilides can be nitrated with very dilute nitric acid.
Aminothiazole and its homologues can be nitrated in the same way, using a double excess of nitrating mixture.
