Vorschrift

To a stirred solution of compound 1F in dioxane (50 mL) and 2M KH2PO4 (50 mL) was added NaBH4 (1.0 g, 26.4 mmol) over a 10 min-period, and the stirring was continued at RT for 1 hr. The reaction mixture was diluted with 2M HCl to adjust pH to 1, and stirred at RT for another 1 hr. The reaction was concentrated, dissolved in EtOAc, washed with water, dried over Na2SO4, and concentrated. Purification by silica gel chromatography (50% EtOAc in hexanes) provided the title compound (1.9 g) as a pale yellow oil.
