A solution of 4-({[1,6-diethyl-4-(tetrahydro-2H-pyran-4-ylamino)-1H-pyrazolo[3,4-b]pyridin-5-yl]methyl}amino)-4-oxobutanoic acid (1.0 g, 2.478 mmol), 1-(3-bromo-4-fluorophenyl)methanamine (0.648 g, 2.69 mmol), HATU (1.065 g, 2.8 mmol) and triethylamine (0.781 mL, 5.6 mmol) in dichloromethane (45 mL) was stirred overnight at room temperature. The reaction mixture was diluted with DCM, washed with saturated NaHCO3, water and saturated NaCl, and dried over Na2SO4. The organic layer was evaporated to give a pale amber residue. The residue was triturated with a small amount of DCM, then sonicated to give a uniform mixture. A white solid was collected and dried to afford N-[(3-bromo-4-fluorophenyl)methyl]-N′-{[1,6-diethyl-4-(tetrahydro-2H-pyran-4-ylamino)-1H-pyrazolo[3,4-b]pyridin-5-yl]methyl}butanediamide (1.08 g, 73.9%) as a crystalline solid. LC-MS m/z 589.1 (M+H)+, 0.79 min (ret time).
