Abstract£º
Purpose£ºsynthesize 5-hydroxyindole
Method: take 3-methyl-4-nitro-phenol as substrate, then treat it with hydroxy group protection, nitroreduction, ring-closure reaction and catalytic debenzylation,finaly get 5-hydroxyindole as product.
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
