The crystal structure of the title compound (C₂₄H₂₂N₂O₅, M_r=418.44) has been determined by single-crystal X-ray diffraction. The crystal is of orthorhombic, space group P2₁/c with a=7.751(2), b=12.392(4), c=21.326(6)Å, V=2048.4(1)Å³, Z=4, D_c=1.357 g/cm³, F(000)=880, μ(MoKα)=0.096 mm^-1, the final R=0.0731 and wR=0.1982 for 3335 observed reflections (I>2σ(I)). Intermolecular C(24)-H(24B)…O(1) hydrogen bond is observed in the structure.
