The present invention relates to a novel method for preparing an itopride·hydrochloride mediate of the formula 1, which is useful for digestive tract activator, and more particularly, the present invention provides with a method for preparing 4-[2-(dimethylamino)ethoxy]benzylamine of the formula 1, an itopride·hydrochloride mediate, whereby being capable of manufacturing in a high yield and lowering cost through a simple purification and a selective reaction, and the method is harmless and safe to human and environment due to not generating toxic gas. And specially, a super-high pressure hydrogenation and a reduction reaction using a metal catalyst are not carried out, therefore, it is very safe method, and also special manufacturing equipments are not needed.
