반응 단계
Compound 77 (1.5 g, 2.26 mmol) was coevaporated with anhydrous toluene (25 mL). To the residue N,N-tetraisopropylammonium tetrazolide (0.127 g, 1.13 mmol) was added and the mixture was dried over P2O5 in a vacuum oven for overnight at 40° C. The reaction mixture was dissolved in acetonitrile/dichloroethane (10 mL) and 2-cyanoethyl-N,N,N′,N′-tetraisopropylphosphorodiamidite (1.362 g, 1.49 mL, 4.52 mmol) was added. The reaction mixture was stirred at ambient temperature for overnight. The completion of the reaction was ascertained by TLC (Rf=0.4 in 1:1 ethyl acetate:hexane). The reaction mixture was concentrated undervacuum and the residue was dissolved in ethyl acetate (100 mL). The organic layer was washed with 5% NaHCO3 (100 mL) and brine (100 mL). The organic layer was dried over anhydrous Na2SO4 filtered and concentrated under reduced pressure. The residue was purified over silica gel (50:49:1, EtOAc:Hexane:triethlyamine) to afford compound 78 as white solid (1.66 g, 85%).
