| titleOfInvention | Synthetic method of 5-aminolevulinic acid hydrochloride |
| abstract | The invention discloses a synthesis method of 5-aminolevulinic acid hydrochloride, which is characterized by comprising the following steps: (1) taking a compound A as a raw material, deprotonating the compound A by alkali, and reacting the deprotonated compound A with succinic anhydride to generate a compound B (ii) a (2) Hydrolyzing the compound B under acidic condition to obtain a target compound (ii) a Wherein R is 1 Is phenyl; r 2 Is phenyl; r 3 Is alkyl, benzyl or substituted benzyl. The synthetic route of the invention is simple and only needs two steps, the synthetic period is short, and the production cost is reduced. The method adopts the classical reaction, has mild reaction conditions, is easy to operate, is beneficial to industrial production, and improves the production safety. The reaction raw materials are easy to obtain. |
