실험 절차

Compound 44a (9.0 g, 13.57 mmol) was coevaporated with anhydrous toluene (50 mL). To the residue N,N-tetraisopropylammonium tetrazolide (0.766 g, 6.8 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 dichloromethane (20 mL) and 2-cyanoethyl-N,N,N′,N′-tetraisopropylphosphorodiamidite (6.13 g, 6.7 mL, 20.35 mmol) was added. The reaction mixture was stirred at ambient temperature for overnight. The completion of the reaction was ascertained by TLC(Rf=0.7 in 1:1 ethyl acetate:hexane). The reaction mixture was diluted with dichloromethane (100 mL) and 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 45a as white solid (10.5 g, 89%).
