To a solution of 1-(5-(4-(bis(4-methoxybenzyl)amino)-6-methyl-1,3,5-triazin-2-yl)-6-(6-methoxypyridin-3-ylamino)pyridin-3-yl)-2,2,2-trifluoroethanol (0.172 g, 0.266 mmol) in dichloromethane (3.00 mL, 0.266 mmol) was added triethylamine (0.093 mL, 0.664 mmol) and methanesulfonyl chloride (0.042 mL, 0.531 mmol) at 0° C. and the mixture was stirred at the same temperature for 1.5 h. The reaction was quenched with saturated NH4Cl and water at 0° C., and the separated aqueous layer was extracted with DCM (2×10 mL) and the combined organic layers were dried over Na2SO4, and concentrated and dried under vacuum to give the crude 4-(5-(1-chloro-2,2,2-trifluoroethyl)-2-(6-methoxypyridin-3-ylamino)pyridin-3-yl)-N,N-bis(4-methoxybenzyl)-6-methyl-1,3,5-triazin-2-amine (0.177 g, 0.0266 mmol), which was used directly in the next step without further purification.
