该中间体在本合成路线中的序号：(IV)The condensation of (I) with propylene oxide (A) in ethanol at 20 C gives 1-(2-hydroxypropyl)-2-methylimidazole (III), which is acetylated with acetyl chloride in refluxing acetonitrile yielding the corresponding acetate (IV). The nitration of (IV) by means of HNO3 and P2O5 affords 1-(2-acetoxypropyl)-2-methyl-4-nitroimidazole (V), which is finally hydrolyzed with 4N HCl at 90 C.
