: A series of 2-(trifluoroacetamido)imidazo[1,2-a ]- pyridines was prepared and treated with phenyliodine(III) bis(tri-fluoroacetate) (PIFA) in the presence of a variety of thiols leading chemoselectively to the corresponding 3-sulfides. Exposure of these adducts to silica gel in MeOH/CH 2 Cl 2 provides a convenient method for the cleavage of the trifluoroacetamide group.
