반응 조건

반응 단계

1-Chloroethyl chloroformate (83 μL, 0.77 mmol) was added to a solution of 1-benzhydryl-3-isobutoxyazetidine (175 mg, 0.60 mmol) in 1,2-dichloroethane (3 mL) at room temperature. The reaction mixture was then heated up to 70° C. and stirred for 1.5 hours. After cooling down to room temperature, methanol (3 mL) was added and the reaction mixture was heated again to 70° C. and stirred for an additional 1.5 hours. After concentration to dryness, the crude mixture was triturated in pentane (2×5 mL) to give a yellow oil (98 mg, quantitative) which was used in the next step without further purification.
