Procedure
2-Mercaptopyridine (5.84 g) and 6-bromocaproic acid (9.75 g) were dissolved in ethanol (50 ml), and the solution was heated under reflux for 14 hours. After cooling, the reaction mixture was added with water, and adjusted to pH 8 with aqueous sodium carbonate. The deposited oily product was extracted with ethyl acetate, and then purified by silica gel column chromatography (developing solvent: chloroform/ethyl acetate) to obtain 13.6 g of the title compound.
