Procedure
A stirred mixture of 4-(3-amino-4-fluorobenzyl)-2H-phthalazin-1-one (0.1 g, 0.37 mmol; prepared in a manner similar to that described in Example 23), 3-oct-2-enyldihydrofuran-2,5-dione (0.078 g, 0.37 mmol) and toluene (10 ml) was heated under reflux for 20 hours, then the solvent was removed in vacuo to give crude 2-{[2-fluoro-5-(4-oxo-3,4-dihydrophthalazin-1-ylmethyl)phenylcarbamoyl]methyl}dec-4-enoic acid (0.133 g) as an oil which was used without further purification.
