3-[2,2-Dichloro-1-(4-ethoxy­phen­yl)cyclo­propane­carbon­yl]oxazolidin-2-one

The title compound, C15H15Cl2NO4, a cyclo­propane derivative related to the insecticide cyclo­prothrin, was prepared from oxazolidin-2-one and 2,2-dichloro-1-(4-ethoxy­phen­yl)cyclo­propane­carbonyl chloride. The five-membered oxazolidine ring is planar to within 0.045 A; the cyclo­propane ring plane forms approximately equal dihedral angles with the mean planes of the oxazolidine and benzene rings [62.7 (4) and 61.6 (4)°, respectively].
