use	2,3-dimethoxybenzylamine is a very important amine compound, which can be used as a raw material for various industrial resins and products, and is also an important intermediate in the synthesis of drugs and fragrances.
preparation	14.0g anhydrous zinc chloride, 11.0g potassium borohydride and 150ml tetrahydrofuran are added into a 500ml round bottom flask, protected by nitrogen, stirred at room temperature for 2.5 hours, 60ml toluene and 13.0 g2, 3-dimethoxybenzoate are added, part of the solvent is heated and evaporated, reacted at 100 ℃ for 3.5 hours, cooled, and poured into 150mL 10% hydrochloric acid, then add 10% potassium hydroxide solution dropwise to pH 11, filter, extract the filtrate with ether (20ml), combine the extract, dry with anhydrous sodium sulfate, evaporate the ether, distill under reduced pressure, collect 6.72g of fraction at 151~152.5 ℃/13mmHg, and the yield of 2, 3-dimethoxybenzylamine is 71.9%.
