Procedure

To a solution of N6-(2-isopropoxy-5-methyl-4-(piperidin-4-yl)phenyl)-N4-(2-(isopropylsulfonyl)phenyl)-3-methyl-1H-pyrazolo[3,4-d]pyrimidine-4,6-diamine (39 mg, 0.067 mmol) in 5.0 mL of MeOH and 5.0 mL of THF was added drops of AcOH and HCHO [1N in MeOH and THF (v/v: 1/1), 0.12 mmol, 120 μL] sequentially. The reaction mixture was stirred at room temperature for 30 min, then NaB(CN)H3 (6.6 mg, 0.12 mmol) was added and the reaction mixture was stirred for another 1 h. Saturated aqueous NH4Cl was added to the reaction and the reaction mixture was concentrated in vacuo. The crude was partitioned between EtOAc and brine. The organic extracts were concentrated and purified by RP-HPLC to afford N6-(2-isopropoxy-5-methyl-4-(1-methylpiperidin-4-yl)phenyl)-N4-(2-(isopropylsulfonyl)phenyl)-3-methyl-1H-pyrazolo[3,4-d]pyrimidine-4,6-diamine. MS (ES+): 592.3 (MH+).
