Procedure
A solution of N-(4-(3-(4-(bis(4-methoxybenzyl)amino)-6-methyl-1,3,5-triazin-2-yl)-5-((4-(methylsulfonyl)piperazin-1-yl)methyl)pyridin-2-ylamino)phenyl)acetamide (0.140 g, 0.186 mmol) in trifluoroacetic acid (Aldrich) (1.383 mL, 18.62 mmol) and trifluoromethane sulfonic acid (TCI) (0.494 mL, 5.59 mmol) was stirred at rt in a sealed tube for 1 h. The reaction mixture was first neutralized with sat. NaHCO3 then extracted with CHCl3 (2×10 mL). The combined organic layers were dried over MgSO4 and concentrated. The crude product was purified by column chromatography (120 g, 4% MeOH in DCM) to give the product as a yellow solid (0.070 g). m/z (ESI, +ve ion) 512.0 (M+H)+. 1H NMR (300 MHz, CDCl3) δ 11.85 (s, 1H); 8.72 (s, 1H); 8.28 (d, J=0.73 Hz, 1H); 7.68 (s, 2H); 7.48 (d, J=8.48 Hz, 2H); 7.12 (br. s., 1H); 5.43 (br. s., 2H); 3.53 (s, 2H); 3.26 (br. s., 4H); 2.78 (s, 3H); 2.59 (s, 7H); 2.19 (s, 3H).
