実験手順

In a third alternate process for preparing the above named compound, 5-(aminomethyl)-1,6-diethyl-N-(tetrahydro-2H-pyran-4-yl)-1H-pyrazolo[3,4-b]pyridin-4-amine (0.1 mmol) and 2,6-pyridinedicarboxylic acid (0.1 mmol) was dissolved in DCM (3 mL), and HOBt was added (1.0 eq, 14.0 mg) along with EDC (1.0 eq, 19.0 mg). The resultant solution was stirred overnight. The solution was purified by preparative HPLC (Gilson) to yield 6-[({[1,6-diethyl-4-(tetrahydro-2H-pyran-4-ylamino)-1H-pyrazolo[3,4-b]pyridin-5-yl]methyl}amino)carbonyl]-2-pyridinecarboxylic acid. This compound was dissolved in 3 mL of DCM along with 1,1-dimethylethyl (2S)-4-{[5′-(aminomethyl)-2′-fluoro-3-biphenylyl]methyl}-2-methyl-1-piperazinecarboxylate (41.3 mg, 0.1 mmol), followed by the addition of HOBt (1.0 eq, 14.0 mg) and EDC (1.0 eq, 19.0 mg). The resultant solution was stirred overnight and product was purified by preparative HPLC (Gilson) to give 1,1-dimethylethyl (2S)-4-[(5′-{[({6-[({[1,6-diethyl-4-(tetrahydro-2H-pyran-4-ylamino)-1H-pyrazolo[3,4-b]pyridin-5-yl]methyl}amino)carbonyl]-2-pyridinyl}carbonyl)amino]methyl}-2′-fluoro-3-biphenylyl)methyl]-2-methyl-1-piperazinecarboxylate. This compound was then dissolved in 2 mL of dioxane:MeOH (3:1). Three drops of HCl (concentrated) were added to the resultant solution and it was heated at 60° C. for 1 h. The solution was applied to the amine column, rinsed with 10 mL of dioxane:MeOH (3:1) to afford 2.2 mg (2.9%) of the above named product. LC-MS m/z 749 (M+H)+, 1.32 min (ret time).
