In a method for producing a de-dimethoxybenzylated compound by removing a dimethoxybenzyl group from a compound containing a dimethoxybenzyl group bonded to a nitrogen atom in the presence of an acid, the de-dimethoxybenzylated compound is obtained by removing the dimethoxybenzyl group without forming a poorly soluble product resulting from the removed dimethoxybenzyl group. The de-dimethoxybenzylation reaction is carried out in the presence of triphenylphosphine or diethylthiourea.
通过在酸的存在下从含有与氮原子结合的二甲氧基苄基团的化合物中去除二甲氧基苄基团的方法,得到去二甲氧基苄基化合物,该去二甲氧基苄基化合物是通过去除二甲氧基苄基团而不形成由去除的二甲氧基苄基团产生的难溶性产物得到的。在
三苯基膦或
二乙基硫脲的存在下进行去二甲氧基苄基化反应。
