Reaction Steps

500 mg (1.9 mmol) of the compound obtained in Example 24, predissolved in 5cm3 of methylene chloride distilled over phosphorus pentoxide are added dropwise to a mixture, cooled to 0° C., of 380 mg (2.84 mmol)of aluminum chloride and 2.3 g (37.9 mmol) of ethanethiol. After stirring at 0° C. for 1 h, 1.5 eq. of aluminum chloride and 20 eq. of ethanethiol are added again. The mixture is stirred again for 1 h at 0° C. and then poured onto ice, treated with 1N hydrochloric acid and then extracted with dichloromethane. After treatment of the organic phase and purification of the crude product by chromatography on a silica column the expected compound is obtained.
