Procedure

Sodium thiosulfate (0.2 m), sodium iodide (1 g), N-(2-chloroethyl)-3,6-dimethyl-2H-1,4-benzoxazine, water (150 ml), and ethanol (75 ml) were mixed and heated at reflux for 3 hrs. The alcohol was distilled off and the reaction mixture was cooled. The product, a white solid, was collected by filtration and dried in air. The yield was essentially quantitative.
