Imatinib (CAS NO.152459-95-5) was developed by rational drug design. After the Philadelphia chromosome mutation and defective bcr-abl protein were discovered, the investigators screened chemical libraries to find a drug that would inhibit that protein. They identified 2-phenylaminopyrimidine with high-throughput screening, then it is tested and modified by the introduction of methyl and benzamide groups to give it enhanced binding properties, producing Imatinib.
1. Introduction of Imatinib
Imatinib is one kind of white to off-white crystalline or pale yellow powder.

4. Uses of Imatinib
Imatinib is used in chronic myelogenous leukemia (CML), gastrointestinal stromal tumors (GISTs) and a number of other malignancies. Imatinib (originally STI571) is a drug used to treat certain cancers. It is the first member of a new class of agents that act by inhibiting particular tyrosine kinase enzymes, instead of non-specifically inhibiting rapidly dividing cells.
5. Production of Imatinib
N-(5-Amino-2-methylphenyl)-4-(3-pyridyl)-2-pyrimidineamine and 4-(4-Methylpiperazin-1-ylmethyl)benzoyl chloride can used to manufacture Imatinib when them are soluble in Azabenzene. And the condition of this reaction can be taken place under the room temperature and nitrogen. Then stir them, reduced pressure concentration, add water, cooling, filter, filter cake vacuum drying, join methylene chloride - methanol, and filtering. At last, you can get the Imatinib.
