Sodium borohydride → 5-{3-[(1R,2R,3R,5R)-5-Chloro-2-((E)-3-hydroxy-oct-1-enyl)-3-(tetrahydro-pyran-2-yloxy)-cyclopentyl]-propyl}-thiophene-2-carboxylic acid methyl ester

Reaction Steps

NaBH4 (9.2 mg, 0.24 mmol) was added to a solution of ketone 4-3 (59 mg, 0.12 mmol) in methanol (1 mL). The reaction was stirred at room temperature for 2 h and then was quenched by addition of 5 mL 1 M HCl. The resulting mixture was extracted with CH2Cl2 and the combined CH2Cl2 solution was dried (Na2SO4), filtered and evaporated. Purification by flash chromatography on silica gel (ethyl acetate/hexanes) gave the title compound (48 mg, 80%).
