Versuchsvorschrift
Benzhydrylamine (1.04 mL, 6.06 mmol) was added to a solution of (2R*)-2-[(1R*)-1-bromopropyl]oxirane obtained in Example (234a) (1.00 g, 6.06 mmol) in methanol (6 mL), and the mixture was heated under reflux for 17 hours. The reaction solution was concentrated under reduced pressure. Saturated aqueous sodium carbonate solution was added to the resulting residue, followed by extraction with ethyl acetate. The combined organic layers were dried over anhydrous magnesium sulfate. Following filtration, the filtrate was concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (elution solvent: hexane/ethyl acetate=2/1) to obtain 787 mg of the title compound as a colorless oily substance (49%).
