合成路线1
该中间体在本合成路线中的序号:(XIII)2) An alternative method starting from aniline (VII) employed the Meerwein arylation of methyl acrylate (IX) with the intermediate diazonium salt (VIII) in the presence of cuprous oxide. The resulting bromoester (X) was cyclized with thiourea (XI) in Et2O, followed by hydrolysis with HCl in sulfolane to afford (XIII). Finally, acid (XIII) was coupled to benzylamine (V) in the presence of (EtO)2POCN and Et3N.
