Procedure

According to a similar procedure to that described in Example 4-(6), 4-methoxybenzyl 4-[[bis(allyloxy)phosphoryl]oxy]-2,2-dimethylbutyrate (1.24 g, 3.0 mmol) obtained from Example 10-(1) was reacted with anisole (1.8 g, 16.6 mmol) and trifluoroacetic acid (5 ml), and the reaction mixture was worked up to afford 4-[[bis(allyloxy)phosphoryl]oxy]-2,2-dimethylbutanoic acid as a crude product. According to a similar procedure to that described in Example 4-(6), the crude product obtained above was reacted with oxalyl chloride (1.98 g, 15.6 mmol) and N,N-dimethylformamide (15 μl), and the reaction mixture was worked up to afford 4-[bis(allyloxy)phosphoryl]oxy-2,2-dimethylbutyl chloride as a crude product.
