Procedure

To a mixture of (5R)-5-(hydroxymethyl)-4-oxaspiro[2.4]heptane (116 mg, 0.9 mmol) and Et3N (183.8 mg, 1.82 mmol, Shantou Xilong chemical factory) in dry CH2Cl2 (6 mL) at −10° C. under N2, was added MsCl (203 mg, 1.4 mmol, Shanghai Haiqu chemical Ltd.) dropwise via a syringe. After stirring for 2 hrs at rt, the reaction was quenched with water ice (3 mL), and the water phases were extracted with CH2Cl2 (20 mL×2). The combined organic phases were dried over Na2SO4, and concentrated in vacuo to give ((5R)-4-oxaspiro[2.4]heptane-5-yl)methyl methanesulfonate as pale yellow oil.
