Versuchsvorschrift

To a solution of (29) (0.2 mmol, 36.8 mg) in 2 ml dichloroethane was added 0.2 mmol acetaldehyde, followed by 63.6 mg sodium triacetoxyborohydride, and 12 μl acetic acid. After 2 h, the solution was poured into water and extracted with ethyl acetate. The combined extracts were washed with water, dried over sodium sulfate, and the solvent removed by rotary evaporation.
