<p>A novel series of bis (phenylimino dihydro thiazolyl-2<i>H</i>-chromene) derivatives have been synthesized through an efficient one-pot multicomponent approach involving different substituted of 3-(2-bromoacetyl)-2<i>H</i>-chromen-2-ones, phenyl isothiocyanates and <i>para</i>-phenylenediamine in presence of dimethylformamide solvent. The target compounds were obtained in a shorter reaction time through simple reaction work up with good yields. All the synthesized products were characterized by their spectral and analytical data like IR, <sup>1</sup>H NMR, <sup>13</sup>C NMR, Roesy, and mass spectral data.</p
