반응 단계

To a solution of pentanethiol (248 μL, 2.0 mmol) in DMSO (2.5 mL) at 0° C. under nitrogen was added NaH (60% in oil, 80 mg, 2.0 mmol). The suspension was stirred for 0.5 h at 0° C. then treated with 1-(diphenylmethyl)azetidin-3-yl methanesulfonate (317 mg, 1.0 mmol; which may be prepared as described in Step 1) and the mixture allowed to warm to room temperature overnight. Saturated NaHCO3 (5 mL) was added and the mixture was extracted with diethyl ether. The organic layer was separated from the aqueous and the organic washed with brine, dried over Na2SO4 and concentrated to give the product (312 mg, 96%) as a yellow oil.
