Procedure
The compound of Example 1 (2.0 g) was suspended in benzene (20 ml) and heated to reflux in the presence of 2-vinylfuran (2.5 ml). Triethylamine was added and the mixture was allowed to reflux for 1 hour longer. The mixture was partitioned between water and ethyl acetate. The ethyl acetate layer was dried over magnesium sulfate and concentrated. Chromatography on silica gel (5:1 hexanes/ethyl acetate) gave the title compound (1.8 g). NMR (CDCl3) 7.3 to 6.9 (m, Ar-H, 5H); 6.2 (m, Furan-H, 2H); 5.5 (dd, CH, 1H); 3.9 (s, OCH3, 3H); 3.6 (m, CH, 1H); 3.4 (m, CH3, 1H).
