    • PURPOSE: A process for preparing cefuroxime axetil in amorphous form is provided which produces highly pure amorphous cefuroxime axetil in high yields by using water added organic/inorganic salt as a non solvent and reduces the cost of manufacturing because the process to boil up to high temperature is not involved. CONSTITUTION: 5-20 % of crystalline cefuroxime axetil is solubilized with water-miscible organic solvent and adding small quantities of the water containing 0.2-40 % of organic/inorganic salt thereto follows to precipitate at the temperature of 20-30°C. The organic/inorganic salt inhibits the production of crystalline cefuroxime axetil by increasing the polarity of non solvent.
    • 目的:提供一种以无定形形式制备头孢呋辛酯的方法,该方法通过使用加水有机/无机盐作为非溶剂,以高收率生产高纯度无定形头孢呋辛酯,并且降低了制造成本,因为煮沸至高温 不参与。 组成:将5-20%的结晶头孢呋辛酯用水混溶性有机溶剂溶解,然后向其中加入少量含有0.2-40%有机/无机盐的水,在20-30℃的温度下沉淀 。 有机/无机盐通过增加非溶剂的极性来抑制结晶头孢呋辛酯的产生。

    • PURPOSE: Title compound is prepared which has an anti-inflammatory and an analgesic property. CONSTITUTION: Iodine and silylating agent such as hexamethyl disilazane, hexamethyl disiloxane, hexamethyl disilane, phenylseleno trimethylsilane, phenyltrimethylsilane, allyltrimethylsilane, 3,6-bis£trimethylsilyl|1,4-cyclohexadiene are activated in polar solvent, followed by the reaction with compound(3) having t-butyl protecting group to give the title compound. Thus, 8.24 g t-butyl2-£2,6-dichlorophenyl)amino|phenylacetoxyacetate is dissolved in 100 ml dichloromethane, followed by addition of 3.06 g iodine and 2.53 ml hexamethyldisilazane, and reacted for 2 hours to give 6.23 g 2-£(2,6-dichlorophenyl)- amino|phenylaectoxyacetic acid.
