To a solution of 1-diphenylmethylazetidin-3-ol (300 mg, 1.3 mmol) in DMF (2.6 mL) at 0° C. under nitrogen was added NaH (60% in oil, 56 mg, 1.4 mmol). The suspension was stirred for 0.5 h at 0° C. then treated with benzyl bromide (236 μL, 2.0 mmol). The mixture was allowed to warm to room temperature then heated to 80° C. overnight. The reaction mixture was cooled, acetic acid (20 drops) was added and the mixture concentrated under reduced pressure. The crude material was purified on column chromatography (eluent: Pentane/EtOAc, 95/5 to 70/30) to give the product (104 mg, 24%) as an orange oil.
