Process for the production of aniline derivatives
-
, (2008/06/13)
Industrial process for the efficient production of aniline derivatives which are important intermediates for the manufacture of oxazolidinedione derivatives and tetrahydrophthalimide derivatives which are useful as active ingredients of herbicides. The process starts from 2,4-dihalo-5-aminophenol or bis(2,4-dihalo-5-aminophenyl)carbonate and selectively cycloalkylates or alkynylates the hydroxy group without protecting the amino group, whereby aniline derivatives having the cycloalkyloxy group or alkynyloxy group can be produced in high yield.
