실험 절차

To a suspension of methyl ((3R,4R)-1-(2-chloro-5-cyano-3-((7-cyano-4-(ethyl(4-methoxybenzyl)amino)imidazo[2,1-f][1,2,4]triazin-2-yl)amino)phenyl)-3-hydroxypiperidin-4-yl)carbamate (100 mg, 0.158 mmol) and 4-((di-tert-butoxyphosphoryl)oxy)butanoic acid (141 mg, 0.475 mmol) in DCM (5 mL) at 0° C., was added DCC (98 mg, 0.475 mmol) followed by DMAP (1.936 mg, 0.016 mmol) and stirred at room temperature for overnight. After completion of the starting material (by LC-MS), reaction mixture was diluted with DCM (2 mL) and filtered through celite and filtrate was washed with water and brine. Combied organic extracts were dried over anhydrous Na2SO4, concentrated. The resultant residue was purified by flash chromatography on silica gel using an ISCO system (eluted with 7:3 Hexanes and EtOAc) to afford (3R,4R)-1-(2-chloro-5-cyano-3-((7-cyano-4 (ethyl(4-methoxybenzyl)amino)imdazo[2,1-f][1,2,4]triazin-2-yl)amino)phenyl)-4-((methoxycarbonyl)amino)piperidin-3-yl 4-((di-tert-butoxyphosphoryl)oxy)butanoate (72 mg) as pale yellow solid.
