Reaction Steps
A mixture of trans-2-[3-(2-hydroxy-n-propylsulfonyl)-4-n-propoxy-5-(4-bromobutoxy)phenyl]-5-(3,4,5-trimethoxyphenyl)tetrahydrofuran (64 mg, 0.10 mmol)(Example 19C), imidazole (27 mg, 0.40 mmol) and potassium carbonate (55 mg, 0.40 mmol) in acetone (3 mL) was heated with stirring at 60° C. under nitrogen for 24 h. The reaction mixture was evaporated and the residue was partitioned between dichloromethane and water. The organic layer was washed with water and brine, dried, and evaporated to a residue Purification by preparative TLC (CH2Cl2 -MeOH; 92:8, v/v) gave the title compound: Rf 0.5; MS, m/z 632 M30 . ; NMR (CDCl3) δ 1.28 (bd, CH2CHOHCH3), 6.94 and 7.08 (bs, NCH=CHN).
