Reaction Steps
A mixture of trans-2-[3-(2-hydroxy-n-propylsulfonyl)-4-n-propoxy-5-(2-bromoethoxy)phenyl]-5-(3,4,5-trimethoxyphenyl)tetrahydrofuran (45 mg, 0.073 mmol) (Example 19A), imidazole (25 mg, 0.36 mmol) and potassium carbonate (50 mg, 0.36 mmol) in acetone (2 mL) was heated with stirring at 55° C. under nitrogen for 42 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; 9:1, v/v) gave the title compound: Rf 0.5; MS, m/z 604 M+. ; NMR (CDCl3) δ 7.06 (bd, NCH=CHN), 7.76 (bs, NCH=N).
