Procedure details
Dupont/Merck in their patents and papers always described that trityl losartan of the formula (7) is detritylated to get Losartan. They have used trimethyl tin azide or tri alkyl tin azides for the preparation of tetrazoles. The trityl Losartan of the formula (7) is reacted with mineral acid to give Losartan of the formula (1). The trityl Losartan of the formula (7) is prepared using trimethyl or trialkyl tin azide for the formation of tetrazole nucleus.

Open Reaction Database (ORD) |

Description
|
The Open Reaction Database (ORD) is an open-access schema and infrastructure for structuring and sharing organic reaction data, including a centralized data repository. The ORD schema supports conventional and emerging technologies, from benchtop reactions to automated high-throughput experiments and flow chemistry. Our vision is that a consistent data representation and infrastructure to support data sharing will enable downstream applications that will greatly improve the state of the art with respect to computer-aided synthesis planning, reaction prediction, and other predictive chemistry tasks. |
