ABSTRACT:

The reaction between primary amines and aldehydes and the resulting Schiff bases are well known. In this paper, we propose the synthesis of title compounds by the condensation of 2:5-dimethoxy aniline with substituted benzaldehydes by 3 different methodologies and compare these methods of synthesis in terms of yield, time etc. Thus showing the superiority of green technique i.e. microwave method over the other two methods employed.

KEYWORDS:
