合成路线1
该中间体在本合成路线中的序号:(VII)The condensation of 4-[2-(acetylamino)ethyl]benzenesulfonyl chloride (I) with 1-cyclohexyl-2-iminoimidazolidine (III) by means of NaOH in refluxing acetone gives 1-[[4-(2-acetamidoethyl)phenyl]sulfonyl]-3-cyclohexyl-2-iminoimidazolidine (III), which is hydrolyzed with refluxing 2N HCl yielding 1-[[4-(2-aminoethyl)phenyl]sulfonyl]-3-cyclohexyl-2-iminoimidazolidine (IV). Finally, this compound is acylated with crotonic anhydride (V) in dioxane. The starting products (I) and (II) are obtained as follows: 1) The acetylation of 2-phenylethylamine (VI) with acetic anhydride gives N-(2-phenylethyl)acetamide (VII), which is sulfonated with chlorosulfonic acid yielding compound (I). 2) The reductocondensation of cyclohexanone (IX) with ethylenediamine (VIII) gives N-cyclohexylethylenediamine (X), which is then cyclized with cyanogen chloride to compound (II).
