Abstract
A facile and efficient synthesis of 3-(1H-benzimidazol-2-yl)-chromen-2-ones (3) by condensation of chromen-2-one-3-carboxylates (1) with o-phenylenediamine (2) is being reported. The reaction has been done under microwave as well as under conventional conditions. The structures of all the products have been confirmed by spectral and analytical data.
