According to a similar procedure to that described in Example 13-(2), allyl 4-[(4-methoxybenzyl)oxy]-4-oxobutyl succinate (546 mg, 1.50 mmol) obtained from Example 14-(4) was treated with anisole (0.50 ml) and trifluoroacetic acid (5 ml), to afford 4-[4-(allyloxy)-4-oxobutyryloxy]butyric acid, and then treated with oxalyl chloride (290 mg) to give crude allyl 4-chloro-4-oxobutyl succinate.
