Procedure
(4-(N,N-Dimethylsulfamoyl)phenyl)magnesium bromide (0.48 M in THF) (2545 μL, 1.222 mmol) was added to 5-(4-(bis(4-methoxybenzyl)amino)-6-methyl-1,3,5-triazin-2-yl)-6-(6-methoxypyridin-3-ylamino)nicotinaldehyde (176.4 mg, 0.305 mmol) to give a deep orange solution. The solution was stirred for 16 h and then quenched with MeOH (1.0 mL). The product was extracted into DCM from water, dried (MgSO4), and purified by flash chromatography (0 to 10% to 20% to 30% EtOAc/DCM) to give 4-((5-(4-(bis(4-methoxybenzyl)amino)-6-methyl-1,3,5-triazin-2-yl)-6-(6-methoxypyridin-3-ylamino)pyridin-3-yl)(hydroxy)methyl)-N,N-dimethylbenzenesulfonamide (171.5 mg, 0.225 mmol, 73.6% yield) as a yellow solid. 1H NMR (400 MHz, d6-DMSO) δ 11.51 (s, 1H); 8.74 (s, 1H); 8.30 (dd, J=4.11, 2.54 Hz, 2H); 7.85 (d, J=2.35 Hz, 1H); 7.55-7.72 (m, 4H); 7.26 (d, J=8.22 Hz, 2H); 7.19 (d, J=8.41 Hz, 2H); 6.90 (d, J=8.41 Hz, 2H); 6.83 (d, J=8.61 Hz, 2H); 6.74 (d, J=9.00Hz, 1H); 6.19 (d, J=3.91 Hz, 1H); 5.86 (d, J=4.11 Hz, 1H); 4.68-4.91 (m, 4H); 3.82 (s, 3H); 3.74 (s, 3H); 3.70 (s, 3H); 2.56 (s, 6H); 2.54 (s, 3H). m/z (ESI, +ve ion) 763.1 (M+H)+.
