3-Iodo-1H-pyrazolo[3,4-d]pyrimidin-4-amine Chemical Properties,Usage,Production

Description

3-Iodo-1H-pyrazolo[3,4-d]pyrimidin-4-amine is a key intermediate in the synthesis of ibrutinib.

Uses

3-Iodo-3H-pyrazolo[3,4-d]pyrimidin-4-amine acts as a reagent in the discovery and preparation of CHMFL-FLT3-122 as potent and orally available FLT3 kinase inhibitor for FLT3-ITD positive acute myeloid leukemia. Development and preparation of potent and selective Plasmodium falciparum calcium-dependent protein kinase 4 (PfCDPK4) inhibitors that block the transmission of malaria to mosquitoes.

Synthesis

A solution of 3H-pyrazolo[3,4-d]pyrimidin-4-amine (10 g, 0.074 mol) and n-iodo-succinamide (25 g, 0.111 mol) in DMF (80 mL) was heated to 80° C. overnight under an argon atmosphere. The resulting solid was filtered and rinsed with cold EtOH. The product was dried in vacuo overnight to yield 3-Iodo-1H-pyrazolo[3,4-d]pyrimidin-4-amine (24 g, 100 per cent yield).
