Reaction Steps

75 mg (0.19 mmol) of the compound from Example 103 were introduced into 14 ml of dichloromethane at 0° C., 47 mg (0.19 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). 74 mg (95% of theory) of the title compound were obtained as mixture of diastereomers.
