実験手順
0.59 g (3.41 mmol) chloroperbenzoic acid dissolved in 15 ml dichloromethane was added dropwise to a solution of 1.5 g (3.41 mmol) 104 in 30 ml dichloromethane analogously to example 25 (preparation of 77). 1.24 g (80%) 105 was obtained after flash chromatography on silica gel. 1.24 g (2.72 mmol) 105 was admixed with 5.5 ml ethanol and 5.5 ml 1 N KOH and cooled for 5 hours at room temperature. It was cooled to 0° C. and acidified with 2 N HCl. The precipitated precipitate was suction filtered, washed with water and isohexane and dried in a vacuum, yield: 0.65 g (56%) 55. The sodium salt prepared from 55 and pulverized NaOH in ethanol melted at 91-94° C.
