Versuchsvorschrift

To a suspension of 174 mg (0.4 mmol) of Compound 24 in 8 ml of ethanol, 151 mg (4 mmol) of sodium borohydride were added gradually under ice-cooled stirring. The resulting mixture was stirred under ice cooling for 1 hour and further at room temperature for 13 hours. Water (80 ml) was added to the reaction mixture. The thus-obtained mixture was stirred at room temperature for 30 minutes and then concentrated under reduced pressure. Post treatment and purification were conducted as in Example 15, whereby 151 mg of the title compound were obtained (yield: 86%).
