실험 절차

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-phenylurea (0.0707 g, 0.108 mmol) and trifluoromethanesulfonic acid (TCI) (0.02 mL, 0.225 mmol) in 1 mL of TFA was stirred at rt for 3 h then heated to 50° C. and stirred for 3 h. Then the mixture was heated at 75° C. 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-phenylurea (0.0210 g, 47% yield) as a yellow solid. 1H NMR (400 MHz, d6-DMSO) δ 11.87 (s, 1H); 10.28 (br. s., 1H); 9.30 (s, 1H); 8.71-8.84 (m, 2H); 8.34 (dd, J=4.60, 1.86 Hz, 8.22 (dd, J=9.00, 2.74 Hz, 1H); 7.87 (br. s., 1H); 7.74 (br. s., 1H); 7.47-7.58 (m, 3H); 7.31 (t, J=7.92 Hz, 2H); 7.01 (t, J=7.43 Hz, 1H); 6.92 (dd, J=7.83, 4.69 Hz, 1H); 2.44 (s, 3H). m/z (ESI, +ve ion) 414.0 (M+H)+.
