実験手順

iPr2NEt (0.5 mL) was added into a solution of 6-((6-((4-hydroxybenzyl)amino)-2-(2,2,2-trifluoroethoxy)pyrimidin-4-yl)amino)nicotinic acid (340 mg), tert-butyl (3-amino-2,2-dimethylpropyl)carbamate (316 mg) and TBTU (501 mg) in THF (10 mL). The reaction was stirred at room temperature for 16 hours before being quenched by water (10 mL). The aqueous layer was extracted with EtOAc (3×10 mL). The combined organic phase was dried over MgSO4 and concentrated under vacuum to give the crude product, tert-butyl 3-(6-(6-(4-hydroxybenzylamino)-2-(2,2,2-trifluoroethoxy)pyrimidin-4-ylamino)nicotinamido)-2,2-dimethylpropylcarbamate, which was purified by silica gel chromatography.
