Sodium Carbonate → N-methyl hexanoylhydroxamic acid

Participants

Reaction Steps

Hexanoylchloride (g, 0.1 mole) is added dropwise with stirring and ice-cooling to a mixture of sodium carbonate (10.6 g, 0.1 mole) and N-methylhydroxylamine hydrochloride (8.35 g, 0.1 mole) in methanol (60 ml), the temperature being kept at less than 5° C. After stirring for a further 30 minutes the mixture is filtered and the solvent is removed using a rotary evaporator. The resultant residue is re-filtered and the residue distilled in vacuo to yield N-methyl-hexanohydroxamic acid as an oil, b.p. 87°-90°/0.1 mm.
