A solution of 2-((5-(4-(bis(4-methoxybenzyl)amino)-6-methyl-1,3,5-triazin-2-yl)-6-(6-methoxypyridin-3-ylamino)pyridin-3-yl)(hydroxy)methyl)-4-bromo-N,N-dimethylbenzenesulfonamide (30.0 mg, 0.036 mmol) in DCM (0.5 mL) was treated with TFA (0.5 mL) followed by triethylsilane (0.3 mL). The mixture was stirred at 72° C. for 16 h. An additional 1 mL of TFA was added, the mixture was placed in a sealed tube, and heated at 100° C. for 4 h to give a much darker orange solution. The mixture was concentrated, neutralized with 2 N NH3/MeOH, concentrated and purified by prep HPLC to give 2-((5-(4-amino-6-methyl-1,3,5-triazin-2-yl)-6-(6-methoxypyridin-3-ylamino)pyridin-3-yl)(hydroxy)methyl)-4-bromo-N,N-dimethylbenzenesulfonamide (20 mg, 0.033 mmol, 93% yield) as a yellow solid. m/z (ESI, +ve ion) 601/603 (M+H)+.
