実験手順

100 mg (0.142 mmol, 80% pure) of the compound from Example 77A were dissolved in 2 ml of DMSO, and a solution of 48 mg (0.350 mmol) of sodium dihydrogenphosphate hydrate in 0.7 ml of water was added at RT. A solution of 39 mg (0.342 mmol) of sodium chlorite in 0.3 ml of water was then added dropwise. The reaction mixture was stirred at RT for 24 h and then diluted with 100 ml of water and extracted three times with in each case about 100 ml of ethyl acetate. The combined organic extracts were washed with saturated sodium chloride solution, dried over anhydrous magnesium sulphate, filtered and freed from the solvent on a rotary evaporator. The crude product obtained in this manner was purified by preparative HPLC (Method 32). After evaporation of the product fractions, the residue was stirred in a mixture of 2 ml of pentane, 0.5 ml of dichloromethane and 0.5 ml of diisopropyl ether for 10 min. Filtration with suction and drying of the solid under high vacuum gave 43 mg (52% of theory) of the title compound.
