실험 절차
A solution of 0.5 g (1.63 mmol) of Aldehyde 1 in 10 mL of THF was treated with 1.1 mL (3.3 mmol) of methylmagnesium iodide (3.0 M in diethyl ether) at −78° C. and was allowed to warm to rt over 30 min. The resulting mixture was quenched with 5 mL of 1 N HCl and was extracted with 30 mL of ethyl acetate. The extract was washed, dried and concentrated to afford the title compound: ESI-MS 323 (M+H); LC-1: 4.2 min.
