  • 用途一:医药中间体,用于半合成或全合成制取后马托品氢溴酸盐。
  • 下游产品:
  • 方法一:由扁桃酸乙酰化反应得到乙酰基扁桃酸,再经氯化而得。在干燥回流装置中,放入相当于1份扁桃酸乙酰化所得乙酰基扁桃酸(约1.29份)。再加2.38份二氯亚砜,于60-65℃反应2.5h,反应放出产生的氯化氢及二氧化硫气体。然后升温至60-70℃,减压回收过量的二氯亚砜。再加无水苯1.8倍量,减压共沸蒸馏,蒸出多余的二氯亚砜和乙酰氯,至蒸馏温度逐渐升至80℃,且已无苯馏出时,再加无水苯1.2倍量,再减压蒸馏一次,至蒸馏温度逐渐升至90℃为止。得淡黄色油状物,即乙酰扁桃酰氯。得量约为扁桃酸的1.44倍。
