Reaction Steps
To a mixture of (R)-tetrahydrofuran-3-ol (1 g, 11.4 mmole) and TEA (2.3 g, 22.8 mmole) in DCM (20 mL) at 0° C. was added dropwise 4-methylbenzene-1-sulfonyl chloride (2.2 g, 11.4 mmole). The resulting mixture was stirred at room temperature for 8 h. The mixture was washed with water, dried over MgSO4, filtered, and concentrated. The crude product was purified by ISCO (silica gel, eluting with 15% ethyl acetate in hexane) to give the title compound (2.3 g). MS (ESI) m/z: Found: 243.3 (M++1). Calc. 242.3 (M+).
