Procedure

To a 25 mL, round-bottomed flask was added N-(3-(4-(bis(4-methoxybenzyl)amino)-6-methyl-1,3,5-triazin-2-yl)-5-((4-(methylsulfonyl)piperazin-1-yl)methyl)pyridin-2-yl)isoquinolin-7-amine (150 mg, 0.201 mmol) and 5% TfOH-TFA (5 mL). The reaction mixture was stirred at 70° C. for 30 minutes and cooled to room temperature. After removal of TFA in high vacuum, the residue was treated with saturated NaHCO3, the obtained suspension was filtered to provide the crude product as a yellow solid. After air drying, the solid was treated with MeOH-DCM-ether and filtered to provide N-(3-(4-amino-6-methyl-1,3,5-triazin-2-yl)-5-((4-(methylsulfonyl)piperazin-1-yl)methyl)pyridin-2-yl)isoquinolin-7-amine (100 mg, 98% yield) as a yellow solid. m/z (ESI positive ion): 506 (M+H)+. 1H NMR (400 MHz, DMSO-d6): 6 ppm 2.88 (s, 3H) 3.09-3.16 (m, 4H) 3.29-3.36 (m, 7H) 3.56 (s, 2H) 7.74 (d, J=5.67 Hz, 1H) 7.83 (br s, 1H) 7.93 (d, J=8.80 Hz, 2H) 8.07 (dd, J=8.90, 2.05 Hz, 1H) 8.36 (d, J=5.67 Hz, 1H) 8.40 (d, J=2.15 Hz, 1H) 8.79 (d, J=2.35 Hz, 1H) 8.87 (d, J=1.56 Hz, 1H) 9.21 (s, 1H) 12.42 (s, 1H).
