achieved via nucleophilicsubstitution of a leavinggroup in the 2-postion with KF or Bu4NF in polar aprotic solvents such as DMF and DMSO. Ionic tetrahydrothiophenium fragment is the most effective leavinggroup, the methanesulfonyl moiety is a somewhat less effective, and Br- and Cl- are the least effective. Relatively mild conditions of the reaction between (2-pyridyl)-tetrahydrothiophenium salts and KF
