Reaction Conditions

Reaction Steps

49.1 mg (1.30 mmol) of sodium borohydride were added to 278 mg (1.18 mmol) of the compound from Example 128A in 23 ml of ethanol and 10 ml of ethyl acetate under argon, and the mixture was stirred at 40° C. for 1 h. The reaction mixture was added to saturated aqueous ammonium chloride solution and ethyl acetate, the phases were separated, the aqueous phase was extracted twice with ethyl acetate, and the combined organic phases were dried over magnesium sulfate, filtered and concentrated. 190 mg (68% of theory) of a mixture of the diastereomerse of the title compound were obtained.
