Procedure

The mixture of 5-(aminomethyl)-1,6-diethyl-N-(tetrahydro-2H-pyran-4-yl)-1H-pyrazolo[3,4-b]pyridin-4-amine (300 mg), 3-[(methyloxy)carbonyl]benzoic acid (180 mg), HBTU (417 mg) and DIPEA (690 μL) in dichloromethane (DCM, 25 mL) was stirred at room temperature overnight. It was concentrated. Separation via CombiFlash (MeOH, DCM) then afforded the desired product (670 mg).
