1,5,6,7-TETRAHYDRO-4H-INDOL-4-ONE CAS 13754-86-4 is Intermediate of propranolol.
Shandong Believe Chemical Pte. Ltd.1,5,6,7-TETRAHYDRO-4H-INDOL-4-ONE CAS 13754-86-4production method：Resorcinol was hydrogenated and isomerized with nickel in the presence of potassium hydroxide to produce potassium 3-keto cyclohexyl-1-enol, which was then combined with ethyl bromopyruvate ring chemicalbook to obtain 4-oxo-4,5,6,7-tetrahydrocoumarone carboxylic Acid-3, and then ammonia was used to replace the oxygen on the furan ring of the latter and eliminate (decarboxylation) to obtain the product.
