Participants

Reaction Steps

80.0 mg (0.22 mmol) of the compound from Example 94 were introduced into 6 ml of dichloromethane at 0° C., 56.1 mg (0.23 mmol) of 70% pure meta-chloroperbenzoic acid were added, and the mixture was stirred at RT overnight. Methanol was added, and the residue after concentration was purified by preparative HPLC (RP18 column; mobile phase: acetonitrile/water gradient with addition of 0.1% formic acid) to result in 43.6 mg (52% of theory) of the title compound as mixture of diastereomers.
