合成路线1
The condensation of 3,4,5-trimethoxybenzaldehyde (I) with 4-methylphenylsulfinic acid (II) and formamide by means of hot CSA gives the adduct (III), which is treated with POCl3 in DME to yield the isonitrile (IV). The reaction of benzaldehyde (V) with methylamine and AcOH in refluxing ethanol gives the enamine (VI), which is finally cyclized with isonitrile (IV) by means of K2CO3 in ethanol/DME to afford the target 1-methylimidazole.
