合成路线1
该中间体在本合成路线中的序号：(I)A new synthesis of [14C]-labeled pantoprazole has been described: The cyclization of potassium [14C]-ethylxanthate (I) with the diaminobenzene (II) by means of NaOH gives the imidazole (III), which is condensed with 2-(chloromethyl)-3,4-dimethoxypyridine (IV) by means of NaOH in ethanol to afford the sulfide (V). Finally, this compound is oxidized with m-chloroperbenzoic acid (mcpba) in dichloromethane.
