Small Molecule Tyrosine Kinase Inhibitors: The New Dawn for Cancer Therapy[J]. Letters in Drug Design & Discovery, 1900, 9(1): 84-125. DOI:10.2174/157018012798192892.
| | Synthesis | Revill P. and co-worker synthesized Axitinib by
iodination of 6-iodo-1H-indazole (100) to give 3,6-di iodo-
1H-indazole (101) ,which on further reaction with 2-
mercapto-N-methylbenzenesulfinamide gives 2-(3-iodo-1Hindazol-6-ylthio)-N-methylbenzamide (101), the same can be
obtained via 2-(1H-indazol-6-ylthion)-N-methylbenzamide
(102) starting from 6-iodo-1H-indazole (100) through
alternative route. N-protection of 2-(3-iodo-1H-indazol-6-
ylthio)-N-methylbenzamide (101) by Boc2, DMAP or DHP,
TsOH gives respective N-protected intermediates 103, 104.
Further treatment of 103, 104 with 2-vinyl pyridine give rise
to N-protected-2-(1-methyl-3-(2-(pyridine-2-yl) vinyl)-1Hindazole-6-ylthio) benzothioamide 105 and 106. Deprotection of 105 and 106 gives destination compound
axitinib (107), the same can be obtained without protection
from 2-(3-iodo-1H-indazol-6-ylthio)-N-methylbenzamide
(101) by simple reaction with 2-vinyl pyridine[1].
