Diethyl (4-tert-butyl-1,3-thiazol-2-ylaminomethylene)malonate

D. E. Lynch and I. McClenaghan

Abstract: The molecule of the title compound, C₁₅H₂₃N₂O₄S, is essentially planar, except for the tert-butyl group, with disorder of the aminomethylene atoms. These are equally disordered over two sites each, giving two alternative intramolecular hydrogen bonds from the partial amine H atoms to the adjacent carbonyl O atoms. An additional, intermolecular, C-HO close contact is observed from the only thiazole ring H atom to one of the carbonyl O atoms.
