実験手順
The mixture of (S)-2-(oxetan-2-yl)ethanol (408 mg, 4 mmol), TsCl (1.15 g, 6 mmol), TEA (0.85 g, 6 mmol) and DMAP (92 mg, 0.8 mmol) in DCM (20 mL) was stirred at RT for 18 h. Then the mixture was concentrated, the residue was dissolved into EtOAc (15 mL), washed with sat. NaHCO3 aqueous solution, water and brine, then the EtOAc layers was dried with Na2SO4, then the solvent was removed under the reduced pressure. The crude product was purified with Combiflash (PE/EtOAc=5/1, silica gel) to give the titled compound.
