实验过程

Linoleyl alcohol (10.0 g, 37.5 mmol) was weighed into a 500 mL round bottomed flask with a stir bar. The flask was sealed, flushed with argon, charged with DCM (100 mL) and triethylamine (7.84 mL, 1.5 equiv.) and cooled to 0° C. Methanesulfonyl chloride (4.35 mL), 1.5 equiv.) was measured in a PP syringe and added slowly to the stirring reaction mixture. TLC analysis (7.5% EtOAc/Hexanes) showed the reaction was complete within 1 hr. The reaction was diluted with DCM (100 mL) and washed with saturated bicarbonate solution (2×200 mL). The organic phase was dried over MgSO4, filtered and concentrated to give 12.53 g (97%) of colorless oil that was used without further purification.
