Abstract
The crystal structure of the title compound (C15H19NO4, MW 277.3 amu) was determined by three-dimensional X-ray analysis from diffractometer data. Crystal data are: monoclinic,P21/n,a=9.600(3) Å,b=11.964(6) Å,c=12.802(4) Å,β=101.25(3)°,V=1442.1(16) Å3,Z=4;D x =1.277 Mg m−3;μ(MoKα)=0.10 mm−1. FinalR=0.055 for 1686 observed reflections having 2θ (MoKα)<50° andI>2.5 σ(I). The compound is isostructural withN-(2-methoxyacetyl)-N-(2,6-xylyl)-3-amino-1,3-oxazolidin-2-one. The dimethylphenyl ring is almost perpendicular to the amidic plane of the molecule (dihedral angle 81.9°); the butyrolactone ring is in the typical envelope conformation.
