실험 절차

To a solution of 1.28 g (4 mmol) of methyl 2,2-dimethyl-4-[3-(3-pyridyl)propyl]8-hydroxyoctanoate in 20 ml methylene chloride at 0° is added 0.9 ml (6.5 mmol) triethylamine followed by 0.4 ml (5.2 mmol) methylsulfonyl chloride. After 1 h, the reaction mixture is diluted with methylene chloride and washed with saturated sodium bicarbonate, water and brine. The organic phase is dried, filtered and evaporated to give methyl 8-methylsulfonyloxy-2,2-dimethyl-4-[3-(3-pyridyl)propyl]-octanoate as an oil.
