실험 절차

A mixture of 113 (1.9 g, 0.005 mol) in THF (200 mL), triethylamine (1.3 mL), and a catalystic amount of 4-dimethylaminopyridine was treated with acetic anhydride (0.9 mL). After stirring over night, the solvent was evaporated and the residue treated with H2O. After 2 h, the mixture was extracted with EtOAc. The extracts were washed with 1 N H2SO4, brine, aqueous NaHCO3 and brine, then the solvent was dried and evaporated to give a floculant white solid (1.94 g) that had the appropriate nmr for the desired material.
