合成路线1
该中间体在本合成路线中的序号：(II)1) The condensation of 4-(3-hydroxypropyl)-1H-imidazole (I) with dimethylcarbamoyl chloride by means of triethylamine in refluxing acetonitrile followed by reaction with trimethylchlorosilane gives 1-(dimethylcarbamoyl)-4-[3-(trimethylsilyloxy)propyl]imidazole (II), which is condensed with 4-cyanobenzyl bromide (III) in refluxing acetonitrile yielding 1-(4-cyanobenzyl)-5-(3-hydroxypropyl)imidazole (IV). The reaction of (IV) with SOCl2 in refluxing dichloromethane affords the corresponding 3-chloropropyl derivative (V), which is finally cyclized by means of potassium tert-butoxide in THF.
