1-Chloroethylchloroformate (361 μL, 3.33 mmol) was added to a solution of 1-benzhydryl-3-(2-(thiophen-2-yl)ethoxy)azetidine (1.11 g, 3.17 mmol) in dichloromethane (15 mL) at room temperature. The reaction mixture was stirred overnight at room temperature, then 1 hour at 70° C. After cooling down to room temperature, ethanol (15 mL) was added and the reaction mixture was stirred at 70° C. for 1 hour. After concentration to dryness, the crude mixture was triturated in pentane (2×15 mL) to give a yellow oil (698 mg, quantitative) which was used in the next step without further purification.
