Sodium hydride → 6-[1-(4-amino-3-methyl-1H-pyrazolo[3,4-d]pyrimidin-1-yl)ethyl]-4-chloro-N-ethyl-3',5'-difluoro-3-methylbiphenyl-2-carboxamide

Participants

Reaction Steps

To a mixture of 3-methyl-1H-pyrazolo[3,4-d]pyrimidin-4-amine (from ChemBridge) (26 mg, 0.17 mmol) in N,N-dimethylformamide (0.5 mL) was added sodium hydride (14 mg, 0.35 mmol). After stirring at room temperature for 30 minutes, to the resulting mixture was added to a mixture of 1-{4-chloro-6-[(ethylamino)carbonyl]-3′,5′-difluoro-5-methylbiphenyl-2-yl}ethyl methanesulfonate (50 mg, 0.1 mmol) in N,N-dimethylformamide (0.5 mL). The reaction was stirred at room temperature overnight and then quenched with water. The resultant mixture was purified on RP-HPLC (XBridge C18 column, eluting with a gradient of acetonitrile/water containing 0.1% ammonium hydroxide, at flow rate of 30 mL/min) to give the desired product. The product was isolated as a racemic mixture. LCMS calculated for C24H24ClF2N6O (M+H)+: m/z=485.2; Found: 485.1
