                                3-Methyltriazolothiazole (2) and 3-phenyltriazolothiazole (3) were regiospecifically lithiated at position 6, triazolothiazole (1) at position 6 and 3 with the former predominating.  The lithiated triazolothiazoles (4), (10) and (11) reacted with a number of electrophiles to give x:6-disubstituted triazolothiazoles, which could be converted into 2,4-disubstituted thiazoles.
