We described an innovative route for synthesis of 2-thioxo-2,3-dihydroquinazolin-4(1H)-ones using isatoic anhydride and phenyl isothiocyanate via in situ formation of anthranilic acid. The reaction was performed in the nano-micellar assembly of surfactant, 4-(dimethylamino)-1-hexadecylpyridinium hydroxide [DAHP]+[OH]- as a nano-reactor. The micelle concentration of surfactant is found to be 0.002 mol
