Procedure

To a solution of 3-chloroaniline (30 mL) in 500 mL of dichloromethane at 0° C. was added dropwise a solution of 4 N HCl in 1,4-dioxane (80 mL). The solution was warmed to room temperature, then concentrated to dryness in vacuo to provide a white powder. A mixture of this powder with 2-oxazolidinone (24.6 g) was heated under nitrogen atmosphere at 160° C. for 10 hours, during which the solids melted, and gas evolution was observed. The reaction was allowed to cool, forming the titled compound 7 as a pale brown solid.
