Reaction Steps

A solution of 4-((5-(4-(bis(4-methoxybenzyl)amino)-6-methyl-1,3,5-triazin-2-yl)-6-(6-methoxypyridin-3-ylamino)pyridin-3-yl)methyl)-N,N-dimethylpiperazine-1-sulfonamide (0.210 g, 0.278 mmol) in trifluoroacetic acid (5 mL, 67.3 mmol) and trifluoromethanesulfonic acid (0.2 mL, 0.278 mmol) was stirred at 80° C. for 2 h. The dark solution was cooled down to room temperature and concentrated to a slurry. The slurry was neutralized to pH 8 with aqueous NaHCO3. The precipitate was dissolved in DCM/MeOH and adsorbed onto a plug of silica gel and chromatographed through a Redi-Sep pre-packed silica gel column (40 g) eluting with a gradient of 5% to 10% 2 M NH3.MeOH in CH2Cl2 to give 4-((5-(4-amino-6-methyl-1,3,5-triazin-2-yl)-6-(6-methoxypyridin-3-ylamino)pyridin-3-yl)methyl)-N,N-dimethylpiperazine-1-sulfonamide (0.110 g, 0.214 mmol, 77% yield). 1H NMR (400 MHz, d6-DMSO) δ 11.75 (s, 1H); 8.70 (d, J=2.15 Hz, 1H); 8.55 (d, J=0.39 Hz, 1H); 8.19 (d, J=2.54 Hz, 2H); 8.17 (dd, J=8.90, 2.84 Hz, 1H); 7.86 (d, J=0.98 Hz, 1H); 7.71 (d, J=1.76 Hz, 1H); 6.82 (d, J=8.80 Hz, 1H); 3.84 (s, 3H); 3.47 (s, 2H); 3.31 (s, 2H); 3.16 (d, J=4.89 Hz, 3H); 2.75 (s, 6H); 2.47 (s, 2H); 2.44 (s, 3H). m/z (ESI, +ve ion) 515.2 (M+H)+.
