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.
在一种通过在酸存在下从含有与氮原子结合的二甲氧基苄基的化合物中去除二甲氧基苄基来生产去二甲氧基苄基化化合物的方法中,去二甲氧基苄基化化合物是通过去除二甲氧基苄基而获得的,不会形成因去除二甲氧基苄基而产生的溶解性差的产物。脱二甲氧苄基反应在
三苯基膦或
二乙基硫脲存在下进行。
