Procedure

A solution of 24-3 (1.419 g, 4.255 mmol) in THF (10 mL) and methanol (5 mL) was treated with sodium borohydride (162.0 mg, 4.282 mmol) and stirred at room temperature (1 h). The reaction was quenched with acetone and the solvent removed in vacuo. Purification via silica chromatography (hexane/ethyl acetate) afforded the title compound 24-4 (1.0 g).
