该中间体在本合成路线中的序号：(II)The acetylation of 4-acetamidophenol (I) with acetyl chloride in refluxing benzene gives 4-acetoxyacetanilide (II), which by a Fries reaction with AlCl3 at 170 C is converted into 2-hydroxy-5-acetamidoacetophenone (III). (1,2) The reaction of (III) with epichlorohydrin (IV) by means of sodium ethoxide in refluxing ethanol affords 1-(2-acetyl-4-acetamidophenoxy)-2,3-epoxypropane (V), which is finally treated with isopropylamine (VI) in refluxing ethanol. (1-3)
