3-[2-(2,3-Dioxoindolin-1-yl)eth­yl]-1,3-oxazolidin-2-one

In the title compound, C₁₃H₁₂N₂O₄, the almost planar (r.m.s. deviation = 0.012 Å) dioxoindolinyl unit and the envelope-shaped oxazolidine ring (with the methyl­ene C atom bonded to the N atom as the flap) are linked by a -CH₂-CH₂- bridge, in which the N-C-C-N unit adopts a gauche conformation [torsion angle = 62.7 (2)°].

S1. Experimental

Indoline-2, 3-dione (1 g, 6.8 mmol), bis(chloroethyl)amine (0.96 g, 6.8 mmol) and potassium carbonate (1 g, 7.2 mmol) along with catalytic amount of tetra-n-butylammonium bromide were stirred in DMF (30 ml) for 72 h. After the completion of the reaction (as monitored by TLC) , the solid material was removed by filtration and the solvent evaporated under vacuum. Dichloromethane (20 ml) was added and the solution filtered. The solvent was removed and the product purified byrecrystallization from ethanol to afford red crystals in 60% yield . The formulation of the product was established by proton and carbon-13 NMR spectroscopy.

S2. Refinement

H-atoms were placed in calculated positions (C—H 0.93–0.97 Å) and were included in the refinement in the riding model approximation, with U(H) set to 1.2–1.5U(C).
