Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 7781-10-4, name is 4-Chloro-7-methyl-7H-pyrrolo[2,3-d]pyrimidine, A new synthetic method of this compound is introduced below., Quality Control of 4-Chloro-7-methyl-7H-pyrrolo[2,3-d]pyrimidine
General procedure: P-aminophenol or 2-fluoro-4-aminphenol 18a-b (0.1 mol)whichwas dissolved in tetrahydrofuran (50 ml),was added to a 1,4-dioxane/H2O(50 ml, 5:1) solution of compounds 17a-b or 20a-b,sodium carbonate and hydrogen sodium at 80 C for 2 h. Then thesolution was concentrated in vacuum and washed with water,filtered to give a solid.
The synthetic route of 7781-10-4 has been constantly updated, and we look forward to future research findings.
