Procedure
To a stirring solution of the compound of example 193 (37 mg, 0.07 mmol) in CH2Cl2 (0.5 ml) was added Dess-Martin reagent (45 mg, 0.105 mmol). After stirring for 30 minutes, solutions of sodium thiosulfate (10% in water, 0.50 ml) and saturated aqueous sodium bicarbonate (0.50 ml) were added simultaneously to the reaction. The mixture was then extracted with dichloromethane (2 times). The organic layer was dried, filtered, and concentrated. The residue was purified by HPLC to yield the two diastereomers of the title compound as solids (first eluting: 7 mg, second eluting: 5.5 mg): MS (ESI) 526.91 (M+H)+.
