    摘要: 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.
