Procedure:
As an alternate process for preparing the compound of Example 131, a mixture of 5-[({[1,6-diethyl-4-(tetrahydro-2H-pyran-4-ylamino)-1H-pyrazolo[3,4-b]pyridin-5-yl]methyl}amino)carbonyl]-3-pyridinecarboxylic acid (50 mg, 0.110 mmol), 1,1-dimethylethyl (2S)-4-{[5′-(aminomethyl)-2′-fluoro-3-biphenylyl]methyl}-2-methyl-1-piperazinecarboxylate (45.7 mg, 0.110 mmol), HBTU (o-benzotriazol-1-yl-N,N,N′,N′-tetramethyluronium hexafluorophosphate) (50.3 mg, 0.133 mmol) and Et3N (0.046 ml, 0.331 mmol) in DCM was stirred at room temperature over the weekend. The reaction was quenched with saturated NaHCO3, and extracted with DCM twice. The combined organic layers were washed with brine and then concentrated under vacuum to give the crude residue. It was then purified with a Gilson HPLC (with 0.1% TFA in the solvents), eluting with 10 to 70% CH3CN in water at a flow rate of 20 mL/min. The product fractions were dried under GeneVac and then combined to give the intermediate 1,1-dimethylethyl (2S)-4-[(5′-{[({5-[({[1,6-diethyl-4-(tetrahydro-2H-pyran-4-ylamino)-1H-pyrazolo[3,4-b]pyridin-5-yl]methyl}amino)carbonyl]-3-pyridinyl}carbonyl)amino]methyl}-2′-fluoro-3-biphenylyl)methyl]-2-methyl-1-piperazinecarboxylate. This intermediate was then dissolved in 2 mL of 25% TFA in DCM and stirred at room temperature for 3 h. The crude products were purified with a Gilson HPLC (with 0.1% TFA in the solvents), eluting with 10 to 70% CH3CN in water at a flow rate of 20 mL/min. The product fractions were combined and the free base was obtained by adding 1 N NaOH, and the aqueous layer was extracted with ethyl acetate twice. The combined organic layers were washed with brine, dried over sodium sulfate, filtered and concentrated under vacuum to N-{[1,6-diethyl-4-(tetrahydro-2H-pyran-4-ylamino)-1H-pyrazolo[3,4-b]pyridin-5-yl]methyl}-N′-[(6-fluoro-3′-{[(3S)-3-methyl-1-piperazinyl]methyl}-3-biphenylyl)methyl]-3,5-pyridinedicarboxamide as a solid (10 mg, 12.1%). LC-MS m/z 748 (M+H)+, 0.70 min (ret time).
