Abstract

The title compound has been synthesized by the reaction of 4 with 1,4-dimethoxybenzene. The yielded product 5 was investigated with X-ray crystallographic, NMR, EI-MS, and IR techniques. The crystal belongs to a monoclinic system, space group P21/c with unit cell parameters a = 12.7790(17) Å, b = 21.565(3) Å, c = 12.2544(16) Å, α = 90°, β = 107.014(2)°, γ = 90°, V = 3229.3(7) Å3, Z = 4, D= 1.661, Mr = 807.32, μ = 2.732 mm−1, F(000) = 1632, R= 0.0540 and wR2 = 0.0989.

Index Abstract
