Product Description

4-Chloropyrrolo[2,3-d]pyrimidine cas number 3680-69-1 is a tofacitinib intermediate for the treatment of methotrexate insufficiency or intolerance of moderate to severe rheumatoid arthritis drug , as well as intermediates commonly used in the synthesis of benzamide c-Met kinase inhibitors. There are two synthetic routes of 4-Chloropyrrolo[2,3-d]pyrimidine, one is usd ethyl cyanoacetate, thiourea, sodium ethoxide as raw materials, and the other is use 2,4-dichloro-7H pyrrolidine as raw material. We have a mature process for both routes.
