To a 25 mL round-bottomed flask was added 4-(5-(1-aminoethyl)-2-(5-fluoro-6-methoxypyridin-3-ylamino)pyridin-3-yl)-N,N-bis(4-methoxybenzyl)-6-methyl-1,3,5-triazin-2-amine (150 mg, 0.246 mmol) and 7% TfOH-TFA (5 mL).The solution was heated at 70° C. for 20 minutes. The mixture was cooled to 0° C. and neutralized with 10N NaOH. The obtained suspension was filtered to provide 4-(5-(1-aminoethyl)-2-(5-fluoro-6-methoxypyridin-3-ylamino)pyridin-3-yl)-6-methyl-1,3,5-triazin-2-amine (80 mg, 88% yield) as a yellow solid. m/z (ESI positive ion): 371 (M+H)+. 1H NMR 400 MHz, DMSO-d6): δ ppm 1H NMR (400 MHz, DMSO-d6) δ ppm 1.07 (d, J=6.26 Hz, 3H) 1.75 (br s, 2H) 2.23 (s, 3H) 3.81-3.86 (m, 1H) 7.60 (d, J=61.62 Hz, 2H) 8.09-8.25 (m, 3H) 8.61 (s, 1H) 11.68 (s, 1H).
