2,3‐Dihydro‐2‐methyl‐1,5‐benzoxazepin‐4(5H)‐ones 5a‐c have been prepared by ring closure of 3‐(2‐aminophenoxy)butyric acids 4a‐c obtained by the reduction of 3‐(2‐nitrophenoxy)butyric acids 3a‐c.
2,3 - 二氢 - 2 - 甲基 - 1,5 - 苯并恶氮杂 - 4 (5H) -ones 5a - c 已通过 3- (2 - 氨基苯氧基) 丁酸 4a - c 的闭环反应制备-(2-硝基苯氧基)丁酸3a-c。
