PROCEDURE

实验过程

To a solution of 1.2 g of methyl 8-(p-chlorophenylsulfonamido)-4-(2-hydroxyethyl)-octanoate (example 28) in 12 ml methylene chloride is added 1.14 g triphenylphosphine followed by 0.336 g 3-hydroxypyridine. After stirring for 5 min, 0.55 ml diethyl azodicarboxylate is added slowly. After 1 h, solvent is evaporated and the residue subjected to flash chromatography to obtain methyl 8-(p-chlorophenylsulfonamido)-4-[2-(3-pyridyloxy)ethyl]-octanoate, m.p. 57°-58°.
