Versuchsvorschrift

A solution of 1-benzhydrylazetidin-3-yl methanesulfonate (324 mg, 1.0 mmol) in thiophene ethanol (2.3 mL, 20.4 mmol) was stirred under microwave irradiations (100 W) at 110° C. for 30 minutes. The reaction mixture was then partitioned between dichloromethane (20 mL) and a solution of sodium hydroxyde (1N, 10 mL). The aqueous layer was separated and extracted with dichloromethane (2×10 mL). The combined organic phases were dried over sodium sulfate, filtered and concentrated to dryness. The residue was purified by chromatography on silica gel, using petroleum ether/ethyl acetate (85:15) as eluent. The title product was obtained as a yellow solid (210 mg, 59%).
