Abstract
2-Pyridinealdoxime methochloride is prepared by forming a mixture of 2-pyridinealdoxime methomethyl sulphate with from 1 to 5 mols of hydrogen chloride per mol of methylsulphate salt, from 0,35 to 1,6 cc. of water per gram of methylsulphate salt, and from 6 to 15 volumes of a water miscible organic solvent to each volume of water. The process may be carried out by: -(a) dissolving 2-pyridine aldoxime metho-methyl sulphate in concentrated hydrochloric acid and then adding the organic solvent, or (b) adding solid 2-pyridinealdoxime methomethylsulphate to a mixture of concentrated hydrochloric acid and organic solvent. The methochloride compound has pharmaceutical properties. 2-Pyridine aldoxime metho-methyl sulphate is prepared by adding dimethyl sulphate to a solution of 2-pyridine aldoxime in acetone and allowing the mixture to crystallise.
