実験手順
tert-Butyl 3-(2,2,2-trifluoroethoxy)azetidine-1-carboxylate (350 mg, 1.37 mmol) in ethyl acetate (1.0 mL) was mixed with 4 M hydrogen chloride-1,4-dioxane solution (3.0 mL) under cooling with ice and then stirred at room temperature for 2 hours. The reaction mixture was concentrated to give a mixture containing the title compound as a colorless oil (224 mg). The mixture was used for next step without further purification.
