2-methylimidazole with arylaldehyde 4 and subsequent reduction of the intermediate 5 with Raney-nickel gave 2-[2-(2,4-dichlorophenyl)ethyl]imidazole 2. Compound 11 was prepared from compound 10 similarly. Reaction of compound 2 with methylsulfonyl chloride gave 1-methylsulfonyl-2-[2-(2,4-dichlorophenyl)ethyl]imidazole (7a) in moderate yield. Nitration of compound 11 (Ar = 3-pyridyl) gave the desired nitro compounds
2-甲基咪唑与芳醛4的缩合,然后将中间体5用阮内镍还原,得到2- [2-(2,4-二氯苯基)乙基]咪唑2。化合物11类似地由化合物10制备。化合物2与甲基磺酰氯反应,以中等收率得到1-甲基磺酰基-2- [2-(2-(2,4-二氯苯基)乙基]咪唑(7a)。硝化化合物11(Ar = 3-吡啶基)得到所需的硝基化合物14和15。
