실험 절차

To a solution of tert-butyl 4-((4-((4-hydroxybenzyl)amino)-6-(2,2,2-trifluoroethoxy)-1,3,5-triazin-2-yl)amino)benzoate (4 g, 8.14 mmol), 1,2-dibromoethane (2.1 mL, 24.42 mmol) in acetone (20 mL) was added potassium carbonate (4.50 g, 32.6 mmol). The resulting solution was stirred for 16 h at reflux. Add another 4 eq of potassium carbonate and 3 eq of 1,2-dibromoethane. The mixture was refluxed for another 7 hs. After cooling to rt, the white solid was filtered and washed with actone. The filtrate was concentrated and purified by Biotage eluting with 20-33% ethyl acetate in hexane to give tert-butyl 4-((4-((4-(2-bromoethoxy)benzyl)amino)-6-(2,2,2-trifluoroethoxy)-1,3,5-triazin-2-yl)amino)benzoate (2.91 g, 60%) as white solid.
