To a 150 mL round-bottomed flask was added 1-(5-(4-(bis(4-methoxybenzyl)amino)-6-methyl-1,3,5-triazin-2-yl)-6-(5-fluoro-6-methoxypyridin-3-ylamino)pyridin-3-yl)ethanone (1 g, 1.640 mmol) and sodium borohydrate (0.06 g, 1.640 mmol) in DCM (10 mL)-MeOH (10 mL). The suspension was stirred at room temperature for 16 h. The solution was quenched by saturated NH4Cl, extracted the aqueous with DCM (3×), the combined organic was dried over MgSO4, concentrated in vacuum to provide 1-(5-(4-(bis(4-methoxybenzyl)amino)-6-methyl-1,3,5-triazin-2-yl)-6-(5-fluoro-6-methoxypyridin-3-ylamino)pyridin-3-yl)ethanol (0.9 g, 90% yield) as a yellow solid. m/z (ESI positive ion) m/z: 612 (M+H)+. 1H NMR (400 MHz, DMSO-d6): 6 ppm 1.36 (d, J=6.46 Hz, 3H) 2.57 (s, 3H) 3.74 (s, 3H) 3.91 (s, 3H) 4.75 (dd, J=6.26, 4.50 Hz, 1H) 4.83 (d, J=12.32 Hz, 4H) 5.25 (d, J=4.30 Hz, 1H) 6.82-6.97 (m, 4H) 7.19-7.35 (m, 4H) 7.98-8.14 (m, 2H) 8.30 (d, J=2.35 Hz, 1H) 8.78 (d, J=2.35 Hz, 1H) 11.68 (s, 1H).
