Versuchsvorschrift
To a mixture of 907 mg (2.0 mmol) of the product of Example 268 in 50 ml of MeOH:THF (4:1) was added sodium borohydride. The reaction was then stilred at room temperature for 30 min and concentrated in vacuo. The residue was dissolved in dichloromethane, washed with 5% HCl and brine, dried over MgSO4, filtered and concentrated in vacuo to provide 872 mg (96%) of the desired product as a white crystalline solid. Electrospray Mass Spec 456 (M+H).
