To a solution (100 ml) of methyl 7-methoxy-3-oxoheptanoate (5.00 g) and 4-(acetylamino)benzenesulfonyl azide (7.02 g) in acetonitrile was added triethylamine (11.1 ml) and the mixture was stirred at room temperature for 2 days. Insoluble material was filtered through celite, and the filtrate was concentrated under reduced pressure. The residue was suspended in diethyl ether and the insoluble material was filtered off. The filtrate was concentrated under reduced pressure to give the object product (6.93 g).
