合成路线1
该中间体在本合成路线中的序号:(V)The cyclization of N-[5-(2-chloroacetyl)furan-2-ylmethylacetamide (I) with thiourea (II) in ethanol gives the thiazole (III), which is condensed with benzoyl isothiocyanate (IV) in acetone to yield the benzoylthiourea (V). The hydrolysis of (V) with NaOH in aqueous methanol affords the thiourea (VI), which is treated with methyl iodide in methanol to give the S-methylisothiourea (VII). Finally, this compound is condensed with 2-ethoxybenzylamine (VIII) in EtOH/AcOH.
