実験手順

5-(4-(Bis(4-methoxybenzyl)amino)-6-methyl-1,3,5-triazin-2-yl)-6-(6-methoxypyridin-3-ylamino)nicotinaldehyde (877.5 mg, 1.519 mmol) was suspended in THF (15 mL) and methylmagnesium bromide (3.0 M in diethyl ether, 1.5 mL, 4.5 mmol) was added. More THF (2.5 mL) was added after about 10 min. After 40 additional min, the reaction was quenched with saturated ammonium chloride and diluted with water (20 mL). The layers were separated, and the aqueous phase was extracted with EtOAc. The organic extracts were combined, dried over sodium sulfate, filtered, concentrated, and purified on a silica gel filter (150 mL fritted filter with about 2 inches of silica gel; 100:1 DCM/MeOH to 40:1 DCM/MeOH) to afford 1-(5-(4-(bis(4-methoxybenzyl)amino)-6-methyl-1,3,5-triazin-2-yl)-6-(6-methoxypyridin-3-ylamino)pyridin-3-yl)ethanol (878.2 mg). 1H NMR (CDCl3, 400 MHz) δ 11.62 (s, 1H), 8.82 (d, J=2.54 Hz, 1H), 8.30 (d, J=2.54 Hz, 1H), 8.26 (d, J=2.74 Hz, 1H), 7.88 (dd, J=8.80 Hz, 2.74 Hz, 1H), 7.21 (dd, J=12.91 Hz, 8.61 Hz, 4H), 6.90-6.82 (m, 4H), 6.71 (d, J=8.80 Hz, 1H), 4.93-4.86 (m, 3H), 4.82 (d, J=6.26 Hz, 2H), 3.93 (s, 3H), 3.82 (s, 3H), 3.79 (s, 3H), 2.58 (s, 3H), 1.72 (d, J=3.91 Hz, 1H), 1.52 (d, J=6.46 Hz, 3H). m/z (ESI, +ve ion) 594 (M+H)+.
