NEW METHOD FOR OBTAINING 8-PYRIDINIOTHEOPHYLLINATES
A new method for the synthesis of 8-pyridiniotheophyllinates by the action of pyridine or alkylpyridines on theophylline or 8-bromotheophylline in the presence of oxidizing agents was developed.The oxidation of 8-bromotheophylline gives the best results.This method was used to obtain 8-(2-methylpyridinio)theophyllinate, which could not be synthesized previously.

REACTION OF 8-BROMOTHEOPHYLLINE WITH PYRIDINE AND ALKYLPYRIDINES. 8-PYRIDINIOTHEOPHYLLINATES
The reaction of 8-bromotheophylline with pyridine or alkylpyridines in the presence of electrophilic reagents proceeds with the formation of 8-pyridiniotheophyllinates.The possible mechanism of the reaction is discussed.
