Procedure

A mixture of phenylacetone (4.92 g, 36.7 mmol) and 4-bromobenzaldehyde (6.78 g, 36.7 mmol) in benzene (40 ml) in the presence of piperidine (0.11 ml, 1.47 mmol) was refluxed for 48 hours. After evaporation, the obtained residue was chromatographed on a column of silica gel (300 g) as eluting with ethyl acetate/hexane (1:20 to 1:2) to afford a yellow solid, which was washed with ethyl acetate/hexane to give 4.22 g (38%) of the title compound as a pale yellow solid.
