Procedure

550 mg of methyl N,N-di-isopropyloxamate was dissolved in 20 ml of methanol. The resulting solution was stirred under ice-cooling, to which 15 ml of 1N aqueous solution of sodium hydroxide was added dropwise. After completion of the dropwise addition, the resultant mixture was stirred for 1 hour at room temperature. The solvent was distilled off from the resulting reaction solution under reduced pressure. The residue was added with 20 ml of 1N HCl. Insoluble white precipitates were collected by filtration, washed with chilled water and n-hexane, and then dried to obtain 180 mg of the title compound, N,N-di-isopropyloxamic acid as white solids.
