실험 절차

1,8-Diazabicyclo[5.4.0]undec-7-ene (3.4 mL, 22.86 mmol) was added to a solution of 6-oxoheptanoic acid 23 (1.1 g, 7.63 mmol) in acetone (15 mL) at 23° C. After stirring for 15 min iodomethane (2.4 mL, 38.3 mmol) was added. The reaction was stirred for 1 h and then the solvent was removed in vacuo. The residue was purified by flash column chromatography (silica gel, 7:3 hex/EtOAc) to provide 1.18 g (95%) of the methyl ester 24 (see scheme 4).
