実験手順

A stirred solution of 1-(diphenylmethyl)-3-azetidinylmethane sulfonate (12.68 g, 39.9 mmol), 2-tert-butylphenol (6.0 g, 39.9 mmol), tetrabutylammonium bromide (1.29 g, 3.99 g) and sodium hydroxide (15.0 mL of 8.0 M solution in water, 120 mmol) in toluene (40 mL) was heated at 100° C. for 5 h. Then, the reaction mixture was cooled to room temperature, diluted with ethyl acetate and separated. The organic layer was washed with water, saturated sodium chloride, dried (Na2SO4), filtered and concentrated under reduced pressure. Purification by flash column chromatography (silica gel, 100:0 to 98:2 heptane/ethyl acetate) provided impure 1-benzhydryl-3-(2-tert-butylphenoxy)azetidine (9.10 g, 66%) as a yellow oil, which was used without further purification or characterization.
