実験手順

A mixture of 4-bromoaniline (1.75 g, 0.0102 mol) and 2,3-epoxy-propylbenzene (1.77 g, 0.0132 mol) in methanol (40 mL) was heated at reflux for 16 hours. The mixture was cooled to ambient temperature and concentrated under reduced pressure. The residue was purified by flash chromatography on silica using ethyl acetate/n-heptane (1:5) as mobile phase to yield 1-(4-bromoanilino)-3-phenyl-2-propanol (2.2 g, 0.00719 mol) as a colorless oil.
