PROCEDURE

实验过程

One hundred two grams (0.62 mol) of 6-hydroxy-4H-3,1-benzoxazin-2-one are dissolved in 1 liter of dimethylsulfoxide and mixed with 227 gm (1.64 mol) of potassium carbonate and 166 gm (0.73 mol) of 4-acetoxy-butylbromide. The reaction mixture is stirred for six hours at 50° C., and then ice water is added. The precipitate is subjected to suction filtration, washed with water, and dried.
