Synthetic Routes of N-Desmethyl Imatinib

There are several synthetic routes to N-Desmethyl Imatinib, each with its own advantages and challenges.
The following are some of the most commonly used synthetic routes:

1. Strain-promoted Reaction

Strain-promoted reaction is a chemical process that involves the use of a strain-promoter template to control the reaction mechanism and increase the reactivity of the substrate.
This method involves the use of a phenyl-substituted benzimidazole as a strain-promoter, which can facilitate the formation of the imidazole ring in the synthesis of N-Desmethyl Imatinib.

1. Pyrazole-Promoted Condensation

Pyrazole-promoted condensation is another synthetic route to N-Desmethyl Imatinib, which involves the use of a pyrazole-promoter to accelerate the condensation reaction between the hydroxyl group of N-Desmethyl Imatinib and the carbonyl group of another molecule.
This method has been found to be more efficient and less expensive than traditional methods.

1. Direct Amination

Direct amination is a synthetic method that involves the use of an amine-containing compound to form a new amine group in N-Desmethyl Imatinib.
This method is useful for synthesizing N-Desmethyl Imatinib, as it allows for the formation of the imidazole ring and the amine group in a single step.

Challenges Associated with the Synthesis of N-Desmethyl Imatinib

Despite the several synthetic routes available for the synthesis of N-Desmethyl Imatinib, there are several challenges associated with its synthesis.
These include:
