A halide salt of a 1-(hydroxyiminomethyl-1-pyridino)-3-(halomethyl)-2-oxapropane is prepared by adding a pyridinealdoxime to a bis-halomethylether in such a manner that the bis-halomethylether is maintained in excess throughout the addition. This procedure produces the halide salt of a 1-(hydroxyiminomethyl-1-pyridino)-3-(halomethyl)-2-oxapropane in high yield and purity, which facilitates its use as an intermediate in the manufacture of an asymmetrically substituted 1,3-di (1-pyridino)-2-oxapropane, a class of compounds that are generally useful antidotes to various toxic agents. A prominent member of the class is the dimethylsulfonate salt of 1-(2-hydroxyiminomethyl-1-pyridino)-3-(4-carbamoyl-1-pyridino)-2-oxapropane. The use of mercaptoalkyl-functionalized polymers is disclosed as a preferred metal ion scavenger for a final purification step in the manufacture of these compounds.

A simple and straightforward approach has been realized for the direct benzoylation of imidazoheterocycles by oxidative decarboxylation of arylglyoxylic acids in the presence of K2S2O8 as an oxidant. Various functional groups were tolerated on both imidazoheterocycles and arylglyoxylic acids and a wide range of C5-benzoyl-imidazoheterocycles were obtained in good to high yields (50–84%).
