실험 절차
(3R,4R)-(4-Hydroxypyrrolidin-3-yl)methanol (1.18 g) was dissolved in ethanol (25 mL). To this solution, triethylamine (1.40 mL) was added and while the mixture was chilled in a salt/ice water bath, benzyl bromide (1.10 mL) was added dropwise. The mixture was stirred at room temperature for 1 hour and was concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (eluant: ethyl acetate: methanol=20:1) to give (3R,4R)-(1-benzyl-4-hydroxypyrrolidin-3-yl)methanol as a milky white syrup (1.02 g).
