Participants

Reaction Steps

To a solution of methyl trans-4-[(4-chlorophenyl) sulfonyl]cyclohexanecarboxylate (209 mg, 0.81 mol) synthesized in (10B) in methanol (10 ml), 2 N sodium hydroxide (0.5 ml, 1 mmol) was added at room temperature, and the resulting mixture was stirred at the same temperature for 1 hour. Then, to the reaction solution, 2 N hydrochloric acid (0.5 ml, 1 mmol) was added, and extraction was performed once with ethyl acetate. The obtained organic layer was washed with water and a saturated aqueous solution of sodium chloride and then dried over anhydrous sodium sulfate. The solvent was distilled off under reduced pressure, and the obtained residue was purified by silica gel column chromatography (hexane:ethyl acetate=10:90 to 0:100 (v/v)), whereby the title compound was obtained as an oil (180 mg, yield: 73%).
