A micro-reaction system and a method for preparing 2-methyl-4-amino-5-aminomethyl pyrimidine. A Raney nickel catalyst is modified with formalin, and the modified Raney nickel catalyst is filled into a micro-channel reactor of the micro-reaction system. A substrate solution containing 2-methyl-4-amino-5-cyanopyrimidine and a base and hydrogen are transported to the micro-mixer and the micro-channel reactor in sequence for continuous catalytic hydrogenation to obtain 2-methyl-4-amino-5-aminomethyl pyrimidine.

A full continuous flow preparation method of 2-methyl-4-amino-5-aminomethylpyrimidine. A mixed solution of cyanoacetamide, N,N-dimethylformamide and a catalyst is mixed with phosphorus oxychloride in a first micro-mixer, and then the reaction mixture undergoes continuous flow reaction in a microchannel reactor to obtain (dimethylaminomethylene) malononitrile. The reaction mixture is subjected to continuous quenching, extraction and separation, and the organic phase is concentrated, mixed with a methanol solution, and then reacted with an organic base to obtain 2-methyl-4-amino-5-cyanopyrimidine. After the mixed liquid is continuously filtered, the filter cake is dissolved in methanol, mixed with hydrogen in a second micro-mixer, and then transported to a fixed-bed reactor for hydrogenation reaction. The products are concentrated, dried and purified to obtain the desired 2-methyl-4-amino-5-aminomethylpyrimidine.
