2-[N-(2,4-Dimeth­oxy­phen­yl)acetamido]-1,3-thia­zol-4-yl acetate

Abstract: The title compound, C15H16N2O5S, is a product of the reaction of 2-(2,4-dimeth­oxy­phenyl­amino)-1,3-thia­zol-4(5H)-one with acetic anhydride. The presence of the acetyl and acet­oxy groups in the mol­ecule indicates that the starting thia­zole exists as a tautomer in the reaction mixture with exocyclic amino and enol moieties. The acetyl group is tilted slightly from the heterocyclic ring plane [dihedral angle = 4.46 (11)°], while the acet­oxy group is almost perpendicular to this ring [dihedral angle = 88.14 (12)°]. An intra­molecular acet­yl-meth­oxy C-H...O inter­action is noted. In the crystal, mol­ecules are connected into a three-dimensional architecture by C-H...O inter­actions.
