실험 절차

Compound 13 (2 g, 7.754 mmol) was dissolved in dry pyridine (20 mL), 4,4′-dimethoxytrityl chloride (2.9 g, 8.53 mmol) was added and the mixture stirred at room temperature overnight. The reaction was quenched with methanol and taken up in ethyl acetate (200 mL). The ethyl acetate solution was washed twice with saturated sodium bicarbonate solution, once with water, once with brine, and dried over anhydrous sodium sulfate. The solvents were removed under reduced pressure and the residue purified by flash chromatography (7% methanol in dichloromethane). The desired fractions were pooled and concentrated to give Compound 14 (3.0 g) in 80% yield. The structure of Compound 14 was confirmed by 1H NMR & ESMS.
