Reaction Steps

A solution of 4-[2-(cyclooctylamino)-2-oxoethoxy]-alpha-oxobenzeneacetic acid methyl ester (0.4 g) in methanol (40 mL) was treated with 1N sodium hydroxide solution (1.3 mL), and the mixture was stirred at room temperature for 15 minutes. After the solvents were evaporated under reduced pressure, water (20 mL) was added and the solution was acidified with 3N hydrochloric acid, then the aqueous layer was extracted with a mixture of dichloromethane-tetrahydrofuran (30 mL; 2:1). The organic layer was dried (MgSO4), evaporated and the resulting oil was crystallized from diethyl ether-hexane to yield 0.084 g of 4-[2-(cyclooctylamino)-2-oxoethoxy]-alpha-oxobenzeneacetic acid, mp 139°-140 ° C.
