Reaction Steps

To a solution of 5 (989 mg, 2.40 mmol) in toluene (15 mL) at −78° C. (bath temperature) was added dropwise a 1.5 M solution of diisobutylaluminum hydride (DIBAL) in toluene (2.4 mL, 3.6 mmol). After 1 h, methanol (2 mL) and ethyl acetate (2 mL) were added, the solution was warmed to room temperature, added to saturated sodium potassium tartarate (30 mL), and stirred for 30 min. The layers were separated, the aqueous phase was extracted with ethyl acetate (3×30 mL), dried (MgSO4), filtered, concentrated, and chromatographed on a 10 cm tall×26 mm diameter silica gel column eluting with 40% ethyl acetate in hexane to afford 6 (832 mg, 84%).
