The present invention provides pyridine derivatives useful as intermediates of drugs and agricultural chemicals, electrophotographic receptors, dyes and so on. More specifically, the invention relates to novel pyridyltetrahydropyridines and novel pyridylpiperidines, and further to a method of manufacturing pyridine derivatives through reaction between bipyridine derivatives and benzyl halide or benzyloxycarbonyl halide and subsequent reduction of the resultant reaction products with the aid of palladium catalysts, platinum catalysts, ruthenium catalysts or rhodium catalysts.
