220 mg (0.74 mmol) of the compound from Example 32A were dissolved in 3 ml of THF, and 0.74 ml (0.74 mmol) of a 1 M solution of lithium aluminum hydride in THF was added dropwise at 0° C. The mixture was stirred at RT for 1 h. For work-up, 5 ml of a saturated potassium sodium tartrate solution were added with ice cooling, the mixture was diluted with 10 ml of ethyl acetate and the precipitated solid was filtered off. The crude product was purified chromatographically [Method 19]. This gave 188 mg (99% of theory) of the target compound.
