Method for synthesizing benserazide hydrochloride by utilizing fixed bed hydrogenation equipment

The invention discloses a method for synthesizing benserazide hydrochloride by using fixed bed hydrogenation equipment, which is characterized in that a compound 1 reacts with an amino protective agent to carry out an amino protection reaction, so that the subsequent purification is easy, and the dosage of hydrazine hydrate in the synthesis method is small; according to the method, fixed bed hydrogenation equipment is used for synthesis, a fixed bed reactor is filled with a solid catalyst or a solid to realize a heterogeneous reaction process, the catalyst in the fixed bed reactor is relatively fixed, a reaction liquid flows through a bed layer, and the reaction liquid flows through the bed layer by adjusting the flow rate and the reaction pressure; qualified products can be obtained after reaction liquid flows out of the fixed bed, continuous production can be achieved, product deterioration caused by long-time contact of the products and the catalyst can be avoided, the same amount of products can be produced due to continuous production, the reactor size can be very small, the safety problem caused by high-pressure reaction is greatly reduced, the amount of the catalyst used in the reaction is less, and the production cost is reduced.

Synthesis method of benserazide hydrochloride

The invention relates to a synthesis method of benserazide hydrochloride. According to the synthesis method, serine methyl ester hydrochloride is taken as the primary raw material, at first, amino protection reactions are carried out; and then amine-ester exchange reactions, condensation reactions, reduction reactions, and de-protection reactions are performed to obtain high purity benserazide hydrochloride. The synthesis method has the advantages that the raw materials are cheap and easily available, the operation is convenient, the product purity and yield of each step are high, and thus thesynthesis method is suitable for industrial production.
