On March 31, 2016, Song, Guo-Qiang; Qin, Feng; Huang, Xian-Feng; Lv, Xiao-Bing; Yang, Bei published an article.Electric Literature of 73590-85-9 The title of the article was Easy Removal of N-carboxybenzyl (Cbz) Protective Group by Low-Carbon Alcohol. And the article contained the following:
A new method for the removal of benzyloxycarbonyl protective group was established. It was accomplished by using methanol, ethanol or t-butanol as a deprotective reagent, and the scope and limitations of this method were also preliminarily investigated. These results broadened utility of N-Cbz protective group in synthetic chem., especially in synthesis or use of imidazole, benzimidazole, pyrazole or their derivatives The experimental process involved the reaction of 5-Methoxy-2-[[(4-methoxy-3,5-dimethyl-2-pyridyl)methyl]thio]benzimidazole(cas: 73590-85-9).Electric Literature of 73590-85-9
