: The invention discloses a novel process for highly chemoselective reactions of substituted anilines without any detectable reaction at aromatic amino group. The invention also relates to a novel process for preparation of neostigmine methylsulphate via chemoselective reaction of 3-amionphenol and aryl dimethylcarbamates.
