실험 절차

To a solution of 2-chloro-cyclohex-1-enecarbaldehyde (13.6 mmol) in THF at 0° C. was added methyl magnesium bromide (3M in THF; 5.4 mL, 16.32 mmol). The reaction was stirred under N2 for 1 hour, and then iPrOH (2 mL) was added. The mixture was concentrated, and the residue was diluted with 1N aqueous HCl and extracted with EtOAc. The combined organic layers were washed with saturated aqueous NH4Cl, dried over MgSO4, filtered, and concentrated, and the crude material was purified by silica gel chromatography to give the title compound.
