Reaction Steps

70 mg (0.17 mmol) of the compound from Example 104 were introduced into 10 ml of dichloromethane at 0° C., 42 mg (0.17 mmol) of 70% pure meta-chloroperbenzoic acid were added, and the mixture was stirred at RT for 2 h. 2 ml of methanol were added, and the solution was concentrated. The residue was purified by preparative HPLC (mobile phase: acetonitrile/water gradient). 76 mg (99% of theory) of the title compound were obtained as mixture of diastereomers.
