4-[[Bis(allyloxy)phosphoryl]oxymethyl]-3-furoic acid (500 mg, 1.65 mmol) obtained from Example 35-(5) was dissolved in dichloromethane (10 ml), and N,N-dimethylformamide (0.03 ml) and oxalyl chloride (0.7 g, 5.5 mmol) were added thereto. The mixture was stirred at room temperature for 1 hour, and toluene was added thereto, then the solvent was distilled off under reduced pressure to give crude 4-[[bis(allyloxy)phosphoryl]oxymethyl]-3-furoyl chloride.
