Result: the structure of the desired product has been confirmed with 1H-NMR spectrum, and the total yield is 32%. Conclusion: this process is easily to operate, the reaction conditions are mild, and it¡¯s easy to control the product¡¯s quality. Key words: 5-hydroxyindole, synthesize, medical intermediate |
