실험 절차

To a stirred solution of 2.41 g of trans-3,4,4a,5,6,11b-hexahydro-2H-[1]benzoxepino[5,4-b]-1,4-oxazine, prepared in accordance with Example 2, and 3.5 ml of triethylamine dissolved in 50 ml of methylene chloride is added dropwise a solution of 0.85 ml of acetyl chloride dissolved in 25 ml of methylene chloride. The mixture is stirred overnight, washed with a dilute hydrochloric acid solution and dried over anhydrous magnesium sulfate. The volatiles are removed by evaporation leaving an oil which yields the compound trans-4-acetyl-3,4,4a,5,6,11b-hexahydro-2H-[1]benzoxepino[5,4-b]-1,4-oxazine having a mp. of 97°-98° C.
