실험 절차

To Example 12 (10.3 g, 0.0246 mol) in THF (50 mL) cooled in a water bath was added PMe3 (49 mL, 1M in THF). The mixture was stirred for 10 min then the solvent was removed in vacuo. The residue was dissolved in MeOH (30 mL) and 50% NaOH (0.7 mL, aq) was added. The mixture was stirred for 30 min and then concentrated in vacuo. To the residue was added water and brine and then extracted twice with EtOAc. The organic layer was dried over MgSO4, filtered and concentrated in vacuo. The resulting solid was triturated with EtOAc/hexane (100 mL, 1:1) and filtered with EtOAc/hexane rinse, then dried to afford 8.8 g of Example 13.
