2-[1-(2-hydroxyethyl)cyclopentyl]ethanol

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a stirred solution of (1-carboxymethyl-cyclopentyl)-acetic acid (1.0 g, 5.3 mmol) at 0° C. was added borane in THF (20 mL, 1.0 M; 20 mmol) and the resultant reaction mixture was stirred and allowed to come to RT overnight. The reaction mixture was cooled in an ice bath and quenched by dropwise addition of methanol (about 5 mL). The solvent was evaporated under reduced pressure and the residue was partitioned between aqueous sodium bicarbonate and ethyl acetate (about 50 mL, 1:1). The organic phase was dried over Na2SO4, concentrated under reduced pressure and filtered through a bed of silica gel to afford 2-[1-(2-hydroxy-ethyl)-cyclopentyl]-ethanol (800 mg) after evaporation of the eluent. the resultant reaction mixture The reaction mixture was cooled in an ice bath quenched by dropwise addition of methanol (about 5 mL) The solvent was evaporated under reduced pressure the residue was partitioned between aqueous sodium bicarbonate and ethyl acetate (about 50 mL, 1:1) The organic phase was dried over Na2SO4 concentrated under reduced pressure filtered through a bed of silica gel
