(Step 2) To a solution of methyl 2-(cyclopentylsulfonyl)benzoate obtained in Step 1 (4.1 g) in tetrahydrofuran-ethanol (100 ml+10 ml) was added lithium borohydride (500 mg) at 0° C. The mixture was stirred at 60° C. for 3 hr, quenched with 1N hydrochloric acid, and extracted with ethyl acetate. The extract was washed with saturated brine, dried over magnesium sulfate, and filtered. The solvent was evaporated under reduced pressure to give [2-(cyclopentylsulfonyl)phenyl]methanol (3.1 g).
