Participants

Reaction Steps

64.0 mg (0.17 mmol) of the compound from Example 43 were introduced into 10 ml of dichloromethane at 0° C., 42.3 mg (0.17 mmol) of 70% pure meta-chloroperbenzoic acid were added, and the mixture was stirred at RT overnight. It was concentrated, and the residue was purified by preparative HPLC (RP18 column; mobile phase: acetonitrile/water gradient with addition of 0.1% formic acid) to result in 54 mg (79% of theory) of the title compound as mixture of diastereomers.
