lpyridine (2) yield 5-chloro-3-tris(trifluoroethoxyl) methyl pyridine (2a) and a dimethyl ketal of 3-chloronicotinic acid anhydride (2b) with fluorines as leavinggroups, respectively. The corresponding reactions of 2,3-dichloro-5-trifluoromethylpyridine (3) only yield the 2-alkoxy-substituted products Ca and 3b with chloro as the leavinggroup and the 2-dimethylamino product 3c which was formed by
