| titleOfInvention | Preparation method for indole-4-formaldehyde |
| abstract | The invention discloses a preparation method for indole-4-formaldehyde. The preparation method comprises the following steps of: (1) adding 5-amino isoquinoline and acetonitrile into a reaction device and stirring; adding methyl iodide; raising temperature to 70-100 DEG C to react for 0.5-2 hours; and performing post-treatment to obtain 5-amino-2-methyl isoquinoline iodate after complete reaction; and (2) adding the 5-amino-2-methyl isoquinoline iodate, a catalyst and a mixed solvent into a high-pressure reaction device and sealing, reacting under internal pressure of 0.3-2 MPa and at the temperature of 100-140 DEG C for 10-40 hours; and performing post-treatment to obtain the indole-4-formaldehyde after complete reaction. The method has the advantages of simple process, high yield, short production period, less catalyst, less solvent and low production cost. |
