実験手順

A toluene solution (5 mL) of 3-(1,1,2,2-tetrafluoroethoxy)benzaldehyde (0.45 g, 2.0 mol) and N-(3-phenoxyphenyl)-3-amino-1,1,1-trifluoro-2-propanol (0.60 g, 2.0 mmol) was refluxed in the presence of molecular sieves and ZnI2 (˜5 mg) for 18 h under N2. The reaction mixture was filtered to remove the sieves, and the filtrate was diluted with ethyl acetate. The organic layer was washed with brine, dried (MgSO4) and evaporated to give 0.92 g (92%) of the desired 3-(3-phenoxyphenyl)-2-[3-(1,1,2,2-tetrafluoro-ethoxy)phenyl]-5-(trifluoromethyl)oxazolidine product as a colorless oil. The formation of the desired product was monitored by the disappearance of the aldehyde peak (δ˜10) in the 1H NMR spectrum. HRMS calcd. 502.1253 [M+H]+, found: 502.1220.
