Reaction Steps

(3R,4R)-1-Benzylpyrrolidine-3,4-diol (Diverchim S. A.; 150 mg, 0.776 mmol) was dissolved in dimethylsulfoxide (4 mL). After adding potassium hydroxide (348 mg, 6.21 mmol), the solution was stirred at 100° C. for 15 minutes. The reaction solution was further stirred at 100° C. for 4 hours after adding a dimethylsulfoxide (4 mL) solution of tetradecyl methanesulfonate (Nu-Chek Prep., Inc.; 568 mg, 1.94 mmol). The mixture was cooled to room temperature, and, after adding water, the aqueous layer was extracted with ethyl acetate. The organic layer was washed with water and a saturated sodium chloride aqueous solution, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure after filtration. The resulting residue was purified by silica gel column chromatography (chloroform 100%) to give compound VI-5 (449 mg, 98.6%).
