Versuchsvorschrift

tert-Butyl 5-(3-(4-(bis(4-methoxybenzyl)amino)-6-methyl-1,3,5-triazin-2-yl)-5-((4-(methylsulfonyl)piperazin-1-yl)methyl)pyridin-2-ylamino)pyridin-2-ylcarbamate (0.306 g, 0.377 mmol) was dissolved into DCM (5 mL total) in two 20 mL scintillation vials. TFA (2.5 mL total) was added and the solutions were stirred at rt for 3 h. The reaction mixtures were combined and poured into 20 mL of saturated aqueous sodium bicarbonate. The aqueous phase was extracted with 25% iPrOH in CHCl3+1% NH4OH (2×20 mL). The combined organic layers were dried over sodium sulfate, filtered and concentrated in vacuo. The crude product was purified by silica gel chromatography (25 g, eluent: iPrOH (w/10% NH4OH) in CHCl3 0%-20%) to give N5-(3-(4-(bis(4-methoxybenzyl)amino)-6-methyl-1,3,5-triazin-2-yl)-5-((4-(methylsulfonyl)piperazin-1-yl)methyl)pyridin-2-yl)pyridine-2,5-diamine (0.221 g, 82% yield) as a yellow solid. 1H NMR (400 MHz, CDCl3) δ 11.44 (br. s., 1H); 8.69 (br. s., 1H); 8.15-8.21 (m, 1H); 8.12 (br. s., 1H); 7.69-7.79 (m, 1H); 7.21 (d, J=8.61 Hz, 4H); 6.85 (dd, J=15.75, 8.51 Hz, 4H); 6.49 (d, J=8.80 Hz, 1H); 4.83 (d, J=15.85 Hz, 4H); 4.27 (br. s., 2H); 3.75-3.85 (m, 6H); 3.48 (br. s., 2H); 3.18 (br. s., 4H); 2.68-2.76 (m, 3H); 2.49-2.61 (m, 7H). m/z (ESI, +ve ion) 711.0 (M+H)+.
