Reaction Steps

0.74 g of sodium hydrogen sulfide (Wako Pure Chemical Industries, Ltd.) was added to a solution of 0.60 mg of 5-oxo-4-(pyridin-2-ylsulfanyl)pentan-2-yl methanesulfonate in 10 mL of N,N-dimethylformamide at a temperature of 0° C. to 10° C., and the obtained mixture was then stirred at the same temperature as described above for 1.5 hours. Thereafter, 30 mL of ethyl acetate and 30 mL of a saturated sodium hydrogen carbonate aqueous solution were added to the reaction mixture, and the water layer was then removed. The organic layer was successively washed with 30 mL of water and a saturated sodium chloride aqueous solution, and was then dried over anhydrous magnesium sulfate. After that, the solvent was distilled away under reduced pressure. The obtained residue was purified by column chromatography (hexane/ethyl acetate=5/1), so as to obtain 120 mg of 5-methyl-3-(pyridin-2-ylsulfanyl)thiolan-2-ol in the form of a light yellow oily product.
