実験手順

A mixture of 1-(diphenylmethyl)-3-azetidinyl methanesulfonate (363.8 g, 1.15 mol), potassium carbonate (330 g, 2.38 mol) and 2-chloro-4-fluorophenol (140 g, 0.96 mol) in acetonitrile (2.5 L) was heated under reflux for 4.5 hours. The cooled reaction mixture was then concentrated in vacuo and the residue was partitioned between ethyl acetate (1 L) and water (500 mL). The organic layer was separated, dried over sodium sulfate concentrated in vacuo and the residue was triturated with ethyl acetate/pentane/dichloromethane, 90:10:1, to afford the title compound as a white solid in quantitative yield, 350 g. 1H NMR(400 MHz, CDCl3) δ: 3.19(m, 2H), 3.75(m, 2H), 4.45(m, 1H), 4.78(m, 1H), 6.60(m, 1H), 6.83(m, 1H), 7.14(m, 1H), 7.18-7.50(m, 10H)
