Reaction Steps

97 mg (0.19 mmol) of the compound of Example 30 is reacted overnight analogously to the synthesis of the compound of Example 6 with 48 mg (0.19 mmol, 70%) of meta-chloroperbenzoic acid. After the crude product is filtered by a Millipore spray filter and the residue is subsequently purified by means of preparative HPLC (mobile solvent: acetonitrile/water gradient), 82 mg (83% of theory) of the title compound is obtained.
