4-Phenylbenzoyl chloride → N-[2-(6-Bromo-2H-pyrazolo[4,3-b]pyridin-2-yl)-1-cyano-1-methylethyl]-biphenyl-4-carboxamide

Participants

Reaction Steps

Using a procedure similar to that described in Example 60, except using a solution of biphenyl-4-carbonyl chloride (0.16 mmole) in THF and a solution of 2-amino-3-(6-bromo-2H-pyrazolo[4,3-b]pyridin-2-yl)-2-methylpropionitrile (0.075 mmole, described in Example 182) in THF mixed with TEA (3% v./v.), the title compound was isolated as solid residue (6.3 mg). It was dissolved in DMSO for further biological evaluation and analyzed by LCMS. MS (ES): M/Z [M+H]=460, RT=0.63 min.
