실험 절차

A mixture of 1-8 (0.068 g, 0.36 mmol), ethylmalonic acid (0.052 g, 0.40 mmol), BOP (0.24 g, 0.54 mmol), and NMM (0.16 mL, 1.4 mmol) in DMF (1.8 mL) was stirred at ambient temperature for 20 h. The mixture was diluted with ethyl acetate, washed with water, brine, and dried over MgSO4. Following evaporative removal of the solvent, the residue was chromatographed on silica gel, eluting with 15% ethanol/EtOAc to give 1-9 as a colorless glass.
