Procedure
1,4-dioxaspiro[4.5]decan-8-ol (1 g, 6.32 mmol) and triethylamine (1.3 mL, 9.48 mmol) taken in anhydrous THF and treated with methanesulfonyl chloride (0.73 mL, 9.48 mmol). Stirred for 18 h. Diluted with water and extracted with EtOAc. The ethyl acetate layer washed with sat NaCl, dried over Na2SO4 and evaporated to give the expected product. Used without further purification.
