An efcient 2-component synthesis of a series of 3-(2-(substituted phenylamino)thiazol-4-yl)-2H-chromen-2- ones (3a-j) was achieved by the reaction of 3-(2-thiocyanatoacetyl)-2H-chromen-2-one (1) with a variety of suitably substituted anilines in 1:1 molar ratio in ethanol. The structures of the products were established by elemental analyses, and UV-vis, FTIR, 1H and 13C NMR, and mass spectroscopy. 3-(2-(4-Methylphenylamino)thiazol-4-yl)-2H-chromen- 2- one (3j) was further characterized by single crystal X-ray diffraction study. This compound, C19H14N2 OS, crystallizes in the orthorhombic space group Pna21, with Z = 4, and unit cell parameters a = 13.0785(11), b = 25.746(2), c = 4.7235(3) A, α=β=γ= 90°. TUeBITAK.
