Triethylamine → 4-Phenyl-1-(3-phenylazetidin-1-yl)butan-1-one

Participants

Reaction Steps

A solution of 3-phenylazetidine (266 mg, 2 mmol) in dry dichloromethane (6 mL) is cooled in an ice bath, and 4-phenylbutyryl chloride (456.6 mg, 2.5 mmol, 1.25 eq) and triethylamine (417 μL, 3 mmol, 1.5 eq) are added. After stirring for 6 hours at room temperature the reaction mixture is diluted with dichloromethane (10 mL). The organic solution is subsequently washed with 1 M KHSO4, 5% NaHCO3 and brine. After drying over Na2SO4, dichloromethane is removed in vacuo and the crude material is purified by flash chromatography (silicagel, ethyl acetate/toluene 1:5). The fractions containing 4-phenyl-1-(3-phenylazetidin-1-yl)butan-1-one are collected and the solvent is removed in vacuo to give 467 mg of colorless oil.
