## Abstract magnified image Synthesis of some novel __N__‐substituted 2‐(chroman/6‐bromochroman‐2‐yl)‐1__H__‐benzimidazoles by the condensation of 3,4‐dihydro‐2__H__‐chroman‐2‐carboxylic acid and 6‐bromo‐3,4‐dihydro‐2__H__‐chroman‐2‐carboxylic acid with __o__‐phenylenediamine in ionic liquid (IL) [
A series of 2-(acyl or carboxyalkyl)-3-(H or alkyl or aryl)-5 (or -6 or -8)-monochloro,7-fluorosubstituted-4H-1,4-benzothiazines 3a-x were prepared to investigate their potential biological activity. In this work the 3a-w structures are supported with physical and analytical data and the results of
