A preparation method of N-(5-methyl furfuryl)benzylamine. The preparation method comprises the following steps: sequentially adding a multi-phase hydrogenation catalyst, 5-methyl furfural, a solvent and benzylamine in a reaction vessel, stirring under a hydrogen atmosphere of which the pressure ranges from normal pressure to 2.0Mpa and the reaction temperature ranging from normal temperature to 100 DEG C, reacting for 0.2 to 0.3 hour, and separating the catalyst and a product. According to the preparation method disclosed by the invention, an operation process is simplified, material loss brought by intermediate steps can be avoided, and maximum utilization of resources is realized; under a proper technological condition, the reaction time is greatly shortened, the production cost is reduced, and the production efficiency is increased; reaction is carried out under a mild condition, requirements on production equipment are not high, and the principle of safety production is met.

Regioselectivity in the intra-molecular Diels-Alder (IMDA) reaction of furfurylcitraconamic acids derived from N-benzylfurfurylamines and citraconic anhydride can be controlled by substituents located in the furan ring and by reaction conditions. Reactions conducted under kinetic conditions resulted in cycloaddition products having methyl and aminomethylene substituent in 1,3-relationship whereas under thermodynamic conditions, excepting in the case of the 3-methylsulfanyl group, the products rearranged to more stable cycloadducts in which the substituents are in 1,2-relationship. Product formation can be explained on the basis of frontier orbital interactions and steric considerations.
