実験手順
To a stirred mixture of 4-(4-nitrobenzylidene)piperidine (23.83 mmol, 5.2 g) and potassium carbonate (31.0 mmol, 4.28 g) in acetonitrile was added a solution of 2-(4-(bromomethyl)phenyl)-1,1,1,3,3,3-hexafluoropropan-2-ol (23.83 mmol, 8.03 g) in acetonitrile. The reaction was stirred for 5 hours then was concentrated under reduced pressure. Dichloromethane was added and the reaction was filtered. The filtrate was chromatographed on silica (eluting with a gradient of dichloromethane to dichloromethane/ethyl acetate) to give the title compound (7.3 g).
