실험 절차

Methyl iodide (0.1 mL, 1.20 mmol) was slowly added to 15 mL of tertiary butyl 3-((3,4-dichlorophenyl)(hydroxy)methyl)azetidine-1-carboxylate (200 mg, 0.602 mmol) and NaH (44 mg, 1.20 mmol) dissolved in a distilled methylene chloride solution at 0° C., and the mixture was stirred for 4 hours. Thereafter, purified water (3 ml) was added thereto, and the mixture was stirred at room temperature for 30 minutes. The reaction mixture was extracted with methylene chloride (3*30 mL), and the organic layer was washed with a saturated sodium chloride solution and distilled water once, respectively and dried over anhydrous magnesium sulfate. The solvent was removed by reduced pressure evaporation to obtain a colorless liquid, which was purified by flash chromatography (n-hexane:ethyl acetate (4:1, v/v)). The product was identified as a single compound by TLC (n-hexane:ethyl acetate (4:1, v/v)).
