AI Technical Summary
Existing FGFR inhibitors suffer from insufficient selectivity and drug resistance in cancer treatment, and also have high toxicity and side effects. There is a need to develop a new generation of FGFR2 and/or FGFR3 inhibitors with high activity and high selectivity.
A process for preparing pyrrolopyrimidine derivatives is provided, which synthesizes the target compound through a multi-step reaction under different solvent and reagent conditions, including the use of acidic and basic reagents, and optimizes the reaction solvent combination to improve the simplicity of operation, cost-effectiveness and product purity.
The preparation of pyrrolopyrimidine derivatives with high yield and high purity has been achieved, making them suitable for industrial production and showing potential application prospects in anti-tumor drugs.
