Abstract
Ethyl 6,7-dimethoxyisoquinoline-1-carboxylate was prepared in an overall yield of 86.4% from homoveratrylamine via amidation, cyclization and oxidation. Its structure was confirmed by1H NMR and13C NMR.The improved process has the advantages of less steps, simple operation and suitable for industrial production.
