合成路线1
该中间体在本合成路线中的序号:(VI)The reaction of beta-chloroethylamine (III) with ammonium thiocyanate (B) gives beta-aminoethylthiocyanate (IV), which is alkylated with alpha,beta-dichloroethylbenzene (V) in hot benzene yielding the secondary amine (VI). The cyclization of (VI) in hot aqueous NaOH affords racemic levamisole, which is finally resolved in its optical isomers through the d-10-camphorsulfonate or N-benzene (or p-toluene)sulfonyl-L-(+)-glutamic salt.
