実験手順

55 mg (0.14 mmol) of the compound of Example 23 is reacted analogously to the synthesis of the compound of Example 6 with 34 mg (0.14 mmol, 70%) of meta-chloroperbenzoic acid for 2 hours at room temperature. After the crude product is purified by means of preparative HPLC (mobile solvent: acetonitrile/water gradient), 53 mg (93% of theory) of the title compound is obtained.
