الإجراء التجريبي

6-Cyano-1-(5-isothiazolyl)-1,2,3,4-tetrahydronaphthalene (Example 26) is converted into the carbanion by treatment with lithium diisopropylamide in THF at -78° and then reacted with N-fluoro-3,3-dimethyl-2,3-dihydro-1,2-benzothiazole-1,1-dioxide. The reaction mixture is allowed to warm to room temperature and is worked up in aqueous medium, yielding the title compound.
