実験手順

A solution of 1-(5-(3-(4-(bis(4-methoxybenzyl)amino)-6-methyl-1,3,5-triazin-2-yl)pyridin-2-ylamino)pyridin-2-yl)-3-(3-fluorophenyl)urea (0.0824 g, 0.123 mmol) and trifluoromethanesulfonic acid (TCI) (0.02 mL, 0.225 mmol) in TFA (1 mL) was stirred at rt for 3 h, 50° C. for 3 h, then 75° C. for overnight. Saturated sodium bicarbonate was added slowly to quench the reaction and the resulting precipitate was collected by filtration. The crude product was purified by preparative HPLC using Phenomenex, Gemni NX 5 micron C18 150×30 mm column (10%-90% CH3CN w/0.1% TFA/H2O w/0.1% TFA in 10 min). The resulting fraction was concentrated to dryness in vacuo. Saturated sodium bicarbonate was added to the residue and the resulting yellow precipitate was collected by filtration, washed with water, and dried in a vacuum oven to give 1-(5-(3-(4-amino-6-methyl-1,3,5-triazin-2-yl)pyridin-2-ylamino)pyridin-2-yl)-3-(3-fluorophenyl)urea (0.0305 g, 58% yield) as a yellow solid. 1H NMR (400 MHz, d6-DMSO) δ 11.89 (s, 1H); 10.49 (br. s., 1H); 9.38 (s, 1H); 8.71-8.83 (m, 2H); 8.29-8.39 (m, 1H); 8.23 (dd, J=9.00, 2.35 Hz, 1H); 7.87 (br. s., 1H); 7.74 (br. s., 1H); 7.47-7.65 (m, 2H); 7.34 (q, J=7.89 Hz, 1H); 7.20 (d, J=8.02 Hz, 1H); 6.92 (dd, J=7.63, 4.69 Hz, 1H); 6.76-6.87 (m, 1H); 2.44 (s, 3H). m/z (ESI, +ve ion) 432.0 (M+H)+.
