1-(Bromomethyl)-4-chlorobenzene(cas: 622-95-7) may be used to synthesize 1-(4-chlorobenzyl)-2-(pyrrolidin-1-yl-methyl)-1H-benzimidazole dihydrochloride.Quality Control of 1-(Bromomethyl)-4-chlorobenzene It can be synthesized by reacting 4-chlorobenzyl alcohol with bromodimethylsulfonium bromide (BDMS) It can also be synthesized by refluxing a mixture of 4-chlorobenzaldehyde, chlorotrimethylsilane, 1,1,3,3-tetramethyldisiloxane and lithium bromide.

In 2019,Organic Letters included an article by Hou, Yuxuan; Hu, Jinjin; Xu, Ruigang; Pan, Shulei; Zeng, Xiaofei; Zhong, Guofu. Quality Control of 1-(Bromomethyl)-4-chlorobenzene. The article was titled 《Indium-Mediated Synthesis of Benzylic Hydroperoxides》. The information in the text is summarized as follows:

An indium(0)-metal-mediated efficient synthesis of benzylic hydroperoxides is described. The reaction proceeds efficiently with a broad range of benzyl bromides under aerobic conditions at room temperature to afford benzyl hydroperoxides in good to excellent yields. In addition, the tandem hydroperoxidn.-Michael addition of (E)-1-(bromomethyl)-2-(2-nitrovinyl)benzene was also demonstrated. In the experiment, the researchers used many compounds, for example, 1-(Bromomethyl)-4-chlorobenzene(cas: 622-95-7Quality Control of 1-(Bromomethyl)-4-chlorobenzene)
