A radical–radical cross-coupling reaction of phenols with tert-butyl nitrite has been developed with the use of water as an additive. This method allows the construction of C–N bonds under an air atmosphere at room temperature, providing the ortho-nitrated phenol derivative in moderate to good yields.
The invention relates to novel diphenylmethane derivatives, processes for their preparation and their use in medicaments, in particular for the indications of arteriosclerosis and hypercholesterolaemia.

A multistage process of preparing N-alkyl-3,4-dialkyl-2,6-dinitroanilines starts from 3,4-dialkyl phenol and goes through the stages of 3,4-dialkyl-2,6-dinitrophenol and 3,4-dialkyl-2,6-ditro alkoxybenzene, wherein the latter are new compounds.
The intermediate ##STR1## wherein R is a lower alkyl group, is used to prepare a N-alkyl-3,4-dialkyl-2,6,-dinitro-aniline in a relatively simple, inexpensive and safe fashion, and with a high yield.
