Hydrogen Peroxide → HCID 86736357, compound

Participants

Reaction Steps

5.2 g of benzonitrile, 18 ml of a 30 percent strength aqueous solution of hydrogen peroxide and 1.0 g of potassium bicarbonate are added to a suspension of 10.1 g of 8-allyloxy2,3-dihydro-(4H)-benz[5.6]oxazin-3-one in 400 ml of methanol and the mixture is then stirred for 3 days at 20°. The reaction mixture is then concentrated to a volume of 40 ml under reduced pressure. After leaving to stand at 0°, 8-(2,3-epoxy-propoxy)-2,3-dihydro-(4H)-benz[5.6]oxazin-3-one is obtained in the form of colourless crystals, which are filtered off and washed with a little cold methanol; melting point 158°-160°.
