Abstract:	The structure of the title compound, C₁₈H₂₀N₂O₅, was determined by X-rays atT=290 K.M _r=344.366, monoclinic, space groupP2₁/c,a=11.4266(5),b=7.9563(15),c=18.9075(7) Å, =101.851(3)°,V=1682.3 Å³,Z=4,D _x=1.360 Mg m^–3. CuK radiation (graphite crystal monochromator, X=1.54178 Å),(CuK)=7.91 cm^–1. Final conventionalR-factor=0.054,R _w=0.073 for 2787 observed reflections and 286 variables. The structure was solved usingMultan.
