A solution of tert-butyl 4-((5-(4-(bis(4-methoxybenzyl)amino)-6-methyl-1,3,5-triazin-2-yl)-6-fluoropyridin-3-yl)methyl)piperazine-1-carboxylate (0.500 g, 0.777 mmol) and 2-methoxypyrimidin-5-amine (0.117 g, 0.932 mmol) (ACES PHARMA) in tetrahydrofuran (10 mL, 123 mmol) was stirred at 0° C. and treated dropwise via syringe with lithium bis(trimethylsilyl)amide (1.0 M solution in tetrahydrofuran; 2.330 mL, 2.330 mmol). The solution was stirred at 0° C. for 1 h. The solution was quenched with water (10 mL) and diluted with water (15 mL) and EtOAc (100 mL). The organic layer was separated and dried over Na2SO4, filtered and concentrated in vacuo to give tert-butyl 4-((5-(4-(bis(4-methoxybenzyl)amino)-6-methyl-1,3,5-triazin-2-yl)-6-(2-methoxypyrimidin-5-ylamino)pyridin-3-yl)methyl)piperazine-1-carboxylate (0.420 mg, 0.561 mmol, 72% yield). m/z (ESI, +ve ion) 749.4 (M+H)+.
