Synthesis, Crystal Structure and Neuroprotection of Methyl 2-((4-(2-(2-Methylphenoxy)acetyl)-piperazin-1-yl)-methyl)benzoate

摘要

A new phenoxyacetamide derivative, methyl 2-((4-(2-(2-methylphenoxy)acetyl)piperazin-1-yl)methyl)benzoate(C22H26N2O4, Mr = 382.45), has been synthesized and characterized by 1H NMR, 13 C NMR, H RMS and single-crystal X-ray diffraction. The crystal is of monoclinic system, space group P21/c with a = 11.145(2), b = 13.667(3), c = 13.998(3)A, β = 112.01(3)o, V = 1976.8(7)A3, Z = 4, Dc = 1.285 g/cm3, F(000) = 816, μ = 0.089 mm-1, MoKα radiation(λ = 0.71073 A), the final R = 0.0602 and wR = 0.1533 for 2343 observed reflections with I > 2σ(I). Intramolecular C–H···O interactions as well as intermolecular C–H···O hydrogen bonds help to stabilize the crystal structure. The preliminary bioassay results show that the title compound exhibits potent neuroprotective activity.
