Procedure
2.2 g (5.9 mmol) of the compound from Example 109 are dissolved in 40 ml of tetrahydrofuran, and 7 ml of glacial acetic acid and 0.96 g (15 mmol) of sodium cyanoborohydride are added. After 14 h at room temperature, the mixture is concentrated in vacuo, the residue is taken up in dichloromethane, and the solution is washed with sodium hydrogen carbonate solution and water, dried over magnesium sulphate and concentrated in vacuo. Purification is carried out by column chromatography on silica gel using dichloromethane/methanol 150/1 as the eluent.
