The title compound （C24 H30O5 ） was synthesized by the reaction of 4-methoxybenzaldehyde and dimedone in ionic liquid [bmim^＋ ][BF4^- ]. Its structure was characterized by elemental analysis, IR, ^1H NMR and X-ray single crystal diffraction. The crystal is of monoclinic, space group P2 1/n with a=0. 887 77（14）, b=1. 154 5（2）, c=2. 100 6（4） nm, β=98. 530（7）°, Mr=398.48, V=2. 129 2（6） nm3 , Dc=1. 243 g/cm^3 , Z=4, μ （Mo Ka） =0. 086 mm^-1 , F（000） 856, R=0. 056 9, Rw=0. 115 9. X-ray analysis reveals that the enol form ring adopts a half-chair conformation. In addition, there are intramolecular hydrogen bonds in the structure.
