Abstract:The dabigatran etexilate was synthesized using 3-[(3-amino-4-methylaminobenzoyl)pyridin-2-ylamino] ethyl propionate and N-(4-cyanophenyl)-glycine as the starting materials through a series of reactions including amidation, cyclization, alcoholysis, aminolysis and acylation with an overall yield of about 68.8%. This synthetic route for dabigatran etexilate has the advantages of simple operation and high yield and is suitable for industrial production. |
Key words:3-[(3-amino-4-methylaminobenzoyl)pyridin-2-ylamino] ethyl propionate; N-(4-cyanophenyl)-Glycine; dabigatran etexilate; thrombembolia |
