실험 절차
A glass microwave reaction vessel was charged with (R)-N-(3-(4-(bis(4-methoxybenzyl)amino)-6-methyl-1,3,5-triazin-2-yl)-5-(1-(4-(methylsulfonyl)piperazin-1-yl)ethyl)pyridin-2-yl)-5-fluoroquinolin-7-amine (82 mg, 0.105 mmol) and trifluoroacetic acid (1 mL, 13.46 mmol, Aldrich). The reaction mixture was stirred and heated in an oil bath at 75° C. for 14 h. The solvent was removed in vacuo. The residue was treated with 10% MeOH/CH2Cl2 (40 mL). The reaction mixture was washed with sat. NaHCO3 (10 mL), saturated NaCl (10 mL) and dried over Na2SO4. The solution was filtered and concentrated in vacuo to give the crude material as a yellow solid. The crude product was purified by silica gel chromatography eluting with 5% MeOH/CH2Cl2 to give (R)-N-(3-(4-amino-6-methyl-1,3,5-triazin-2-yl)-5-(1-(4-(methylsulfonyl)piperazin-1-yl)ethyl)pyridin-2-yl)-5-fluoroquinolin-7-amine (33 mg, 0.061 mmol, 58.2% yield). 1H NMR (300 MHz, CDCl3) δ 1.47 (d, J=6.72 Hz, 3H) 2.52-2.72 (m, 7H) 2.78 (s, 3H) 3.25 (t, J=4.17 Hz, 4H) 3.60 (q, J=6.53 Hz, 1H) 5.49 (s, 2H) 7.12-7.24 (m, 1H) 7.39-7.54 (m, 1H) 7.83 (d, J=8.33 Hz, 1H) 8.48 (d, J=2.19 Hz, 1H) 8.77 (d, J=2.05 Hz, 1H) 8.96 (d, J=2.34 Hz, 1H) 9.25 (d, J=1.90 Hz, 1H) 12.51 (s, 1H). m/z (ESI, +ve ion) 538.1 (M+H)+.
