Reaction Conditions

Reaction Steps

Tetrazole (90.0 mg, 1.28 mmol) was added to tertiary butyl 3-((3,4-dichlorophenyl)(hydroxy)methyl)azetidine-1-carboxylate (200 mg, 0.638 mmol) and triphenylphosphine (335 mg, 1.28 mmol) dissolved in the distilled tetrahydrofuran solution (15.0 mL), and diisopropyl azocarboxylate (0.25 mL, 1.28 mmol) was slowly added thereto at 0° C., and the mixture was stirred at room temperature for one day. The solvent of the reaction mixture was removed by reduced pressure evaporation to obtain a yellow 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)) (yield: 88%, white solid). This white solid was dissolved in 10 mL of methanol solution, and 1 N HCl (3.0 mL) was added thereto, and heated to reflux at 60° C. for one day. Thereafter, the solvent of the reaction mixture was removed by reduced pressure evaporation to obtain the title compound (KHG27280).
