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.
