Abstract:	The structure of the title compound, C₁₈H₂₀N₂O₅, was determined by X-rays atT=290 K.M _r=344.366, orthprombic, space groupP2₁2₁2₁,a=9.350(5),b=11.954(2),c=15.455(3) Å,V _c=1727.3 Å³,Z=4,D _c=1.324 Mg m^–3. CuK. radiation (graphite crystal monochromator, =1.54178 Å),(CuK)=7.70 cm^–1. Final conventionalR-factor=0.065,R _w=0.086 for 2887 observed reflections and 265 variables. The structure was solved usingMultan.
