4-Chloro-7H-pyrrolo[2,3-d]pyrimidine Chemical Properties,Usage,Production

Uses

4-Chloro-7H-pyrrolo[2,3-d] pyrimidine is an important pharmaceutical intermediate, which is widely used in the synthesis of many pharmaceutical intermediates at home and abroad. Including CP690550, CGP76030 and so on, 4-Chloro-7H-pyrrolo[2,3-d] pyrimidine was the scaffold for many commercially available drugs. Also, 4-Chloro-7H-pyrrolo[2,3-d] pyrimidine was the intermediate of the bulk drug, Tofatinib, which was widely used in treatment of adult patients with moderate to severe rheumatoid arthritis with inadequate or intolerant methotrexate response.

Chemical Properties

Lightbrown to brown crystalline powder

Uses

4-Chloro-7H-pyrrolo[2,3-d]pyrimidine is used in the manufacture of Tofacitinib citrate.

Synthesis

The preparation process of pyrimidine includes the first α -alkylation reaction between diethyl malonate and allyl bromide, and the subsequent cyclization reaction with amidine to obtain a six-membered ring of bislactam. The chlorination of carbonyl with phosphorus oxychloride to obtain dichloro pyrimidine ring, followed by the oxidation of the terminal double bond with potassium osmate hydrate and sodium periodate to obtain the aldehyde group. The final reaction with ammonia water to produce SNAr/cyclization reaction, a five-step reaction, total yield of 45.8% to obtain 4-Chloro-7H-pyrrolo[2,3-d]pyrimidine.
