  The invention comprises 2,3,5,6-tetrafluoropyridine -4-carboxylic acid and the preparation thereof by oxidizing 2,3,5,6-tetrafluoro-4-propenylpyridine with nitric acid. The 4-carboxylic acid can be decarboxylated by heating to 2,3,5,6-tetrafluoropyridine. The s-benzylthiouronium derivative of the acid is obtained by reacting the acid with s-benzylthiouronium chloride.

  该发明包括2,3,5,6-四氟吡啶-4-羧酸及其通过用硝酸氧化2,3,5,6-四氟-4-丙烯基吡啶来制备。4-羧酸可以通过加热转化为2,3,5,6-四氟吡啶。酸的s-苄基硫代脲衍生物是通过将酸与s-苄基硫代脲氯化物反应获得的。

  Fluoroheterocyclic aldoximes were screened as therapeutic agents for the treatment of anticholinesterase poisoning. 2-Fluoropyridine-3- and -6-aldoxime, and 3-fluoropyridine-2- and -4-aldoxime, were synthesised. Attempts to obtain 3,5,6-trifluoropyridine-2,4-bis(aldoxime) and -2-aldoxime, however, proved unsuccessful. Pentafluorobenzaldoxime was prepared by oximation of pentafluorobenzaldehyde. Acid dissociation constants (pK(a)) and second-order rate constants (k(ox)-) of the fluorinated pyridinealdoximes towards satin were measured. 2,3,5,6-Tetrafluoropyridine-4-aldoxime had the best profile: its k(ox)- approached that of the therapeutic oxime P2S (310 vs. 120 l mol(-1) min(-1)), but its higher pK(a) (9.1 vs. 7.8) fell short of the target figure of 8 required for reactivation of inhibited acetylcholinesterase in vivo. N-alkylation of the fluorinated pyridine-aldoximes may reduce their pK(a) nearer to 8 and enhance their therapeutic potential. Crown Copyright (c) 2011 Published by Elsevier B.V. All rights reserved.
