Reaction Conditions

Reaction Steps

409 mg (10.8 mmol) of sodium borohydride were added to 2.20 g (9.84 mmol) of the compound from Example 127A in 180 ml of ethanol and 60 ml of ethyl acetate under argon, and the mixture was stirred at 40° C. for 2 h. The reaction mixture was added to dichloromethane, the phases were separated, and the organic phase was washed with water, dried over magnesium sulfate, filtered and concentrated. The crude product was purified by flash chromatography on silica gel (mobile phase: toluene/ethyl acetate gradient) to result in 1.52 g (69% of theory) of a mixture of the diastereomers of the title compound.
