【Abstract】 AIM To study and look for a practical synthetic technique for industrial production of melatonin. METHODS K phthalimide (I) was prepared by phtalimide to generate N (3 brompropyl) phtalimide(II) and ethyl 2 acelyl 5 phthalimido pentanotate(III). Via "Japp Kligeman" reaction and "Fisher reaction", 2 ethoxycarboxyl 3 (2 phthalimido ethyl) 5 methoxy indole (V) was prepared. After saponification, hydrolysis, decarboxylation of V, 5 methoxy trypytamin (IV) was obtained. IV was acetelized to give melatoin (VII). RESULTS The total yield was 20% higher than the reported yield and the quality of product was up to the pharmacy standard. CONCLUSION The results of the present study indicate that the method is practical and cost efficient.更多还原
