A mixture of N5-(3-(4-(bis(4-methoxyb enzyl)amino)-6-methyl-1,3,5-triazin-2-yl)-5-chloropyridin-2-yl)pyridine-2,5-diamine (Example 4, step 2, 0.158 g, 0.277 mmol) and 4-nitrophenyl 4-(2-methoxyethoxy)phenylcarbamate (0.118 g, 0.354 mmol) in DCM (3 mL) was stirred at rt for 3 days. Et3N (0.20 mL) was added followed by 4-nitrophenyl 4-(2-methoxyethoxy)phenylcarbamate (0.142 g, 0.428 mmol). The reaction mixture was stirred at rt for 2 h. The yellow solid was collected and washed with DCM to give 0.176 g of crude 1-(5-(3-(4-(bis(4-methoxybenzyl)amino)-6-methyl-1,3,5-triazin-2-yl)-5-chloropyridin-2-ylamino)pyridin-2-yl)-3-(4-(2-methoxyethoxy)phenyl)urea, which was taken into the next step without further purification.
