Reaction Conditions

Reaction Steps

Triphenylphosphine (3.08 g, 11.76 mmol) was dissolved in anhydrous tetrahydrofuran (THF) (30 ml). Oxygen was completely removed by passing nitrogen through the mixture, and the mixture was cooled to 0° C. Diisopropylazodicarboxylate (2.3 ml, 11.76 mmol) was added thereto, and stirred at 0° C. for 1 hour. Added slowly to the mixture in succession were thioacetic acid (840 μl, 11.76 mmol) and 1-benzyl-azetidine-3-ol (960 mg, 5.88 mmol) prepared in Preparation Example 37 and dissolved in tetrahydrofuran (20 ml). The resulting solution was heated to room temperature, stirred for 2 hours and concentrated under a reduced pressure to remove the solvent. The concentrate was dissolved in ethyl acetate, washed with water, dried over anhydrous magnesium sulfate and concentrated under a reduced pressure. The resulting residue was purified by column chromatography (eluent−ethyl acetate/normal hexane=1/1) to obtain 1.1 g (yield: 83%) of the title compound.
