| titleOfInvention | Preparation method of hypoxanthine |
| abstract | The invention discloses a preparation method of a hypoxanthine, which comprises the steps of methylating the 7-position N and the 1-position N of guanosine (V), hydrolyzing glycosyl to obtain a compound (II), and then reacting the compound (II) with a diazotization reagentAfter reaction, the mixture is hydrolyzed to obtain the hypoxanthine (I). The raw materials and auxiliary materials are cheap and easily available, and the industrial price of the main raw material, namely guanosine is only 90 yuan/KG; the steps are short, and the total yield is more than or equal to 70 percent; the method has the advantages of conventional conversion, mild reaction conditions, safety and reliability; simple operation, stable process and suitability for industrialization. |
