We herein, describe efficient and scalable synthesis of 2,4-diaryl substituted chromene [43-b] pyridine derivatives
using multicomponent reaction strategy by microwave irradiation of 4-amino 2-oxo-2H-chromene, aromatic aldehydes and
substituted anilines. This synthetic strategy was found to be very useful as it follows environment benign protocol, also it
gives good outcome in terms of yield and requires shorter reaction time.
