Procedure
Stir at room temperature for four days 2 gms. of the iodide prepared in Examples 2 or 3, 2 gms. of 2-ethylimidazole, 2.5 ml. DMF and 0.4 gm sodium hydroxide in a reaction flask. Remove the solvent and partition with water/methylene chloride. Elute on a silica column with 100% methylene chloride and then 10% methanol to yield the title compound. MS:m/z 337 (M+) H1 -NMR-200 mHz, εH (CDCl3), 1.34 (3H,t,J 7.5 Hz), 1.3-1.65 (4H,m), 1.70-1.90 (4H,m) 2.66 (2H,q,J 7.5Hz), 3.75 (3H,s), 3.83 (2H,t,J 7Hz), 3.95 (2H,t,J 6Hz), 6.7-7.0 (5H,m).
