The stoichiometry of I was derived from the results of elemental analysis, IR, H-1, C-13-NMR, UV-Vis and mass spectroscopic techniques. The structure derived from physico-chemical methods is consistent with that of the X-ray diffraction. The compound crystallizes in the triclinic system, space group P (1) over bar, with a = 9.3895(12), b = 11.3759(11), c = 12.8077(14) Angstrom, alpha = 103.290(3)degrees beta = 98.110(4)degrees, gamma = 105.545(3)degrees, V = 1252.4(2) Angstrom(3), Z = 2. The molecule has a non-planar configuration. The methoxycarbonylmethyl group exhibits an E-configuration. The crystal structure is stabilized by intermolecular C-H...O, N-H...O and O-H...O contacts.
