Abstract

The invention comprises compounds of the general formul <FORM:0666596/IV (b)/1> and <FORM:0666596/IV (b)/2> wherein R1 is an alkoxy group, the alkyl group of which contains not more than 8 carbon atoms (including iso-alkyl and cyclohexyl groups), R11 is an alkyl group containing not more than 8 carbon atoms (including isoalkyl and cyclohexyl groups, R111 is an alkyl or alkenyl group containing not more than 4 carbon atoms or an aralkyl group, e.g. a benzyl group, and X is a monovalent anion. Preferred monovalent anions are the chloride, bromide, iodide and methyl sulphate radicals. Compounds of formula I are prepared by reacting an alkali metal derivative of b -pyridol with a dialkyl halogenophosphate. Examples describe the preparation of (1) b -pyridyl diethyl phosphate by reacting the sodium salt of b -pyridol with diethyl chlorophosphonate; (2) b -pyridyl di-isopropyl phosphate similarly. The dimethyl compound is also mentioned. The compounds are described as having anticholinesterase activity.
