2-(Acetoxymethyl)-5-[[bis(allyloxy)phosphoryl]oxymethyl]benzoic acid (475.5 mg, 1.24 mmol) obtained from Example 1-(11) was dissolved in tetrahydrofuran (5 ml), and the solution was cooled to 0° C., then oxalyl chloride (189.2 mg, 1.49 mmol) and N,N-dimethylformamide (15 μl) were added thereto with stirring. The mixture was warmed to room temperature and then stirred for 40 minutes. The solvent was distilled off under reduced pressure to give the crude 2-(acetoxymethyl)-5-[[bis(allyloxy)phosphoryl]oxymethyl]benzoyl chloride.
