(Aminooxy)acetic acid → HCID 3372981, compound

Participants

Reaction Steps

4.2 g of 4-chlorobenzaldehyde and 3.3 g of hemihydrochloride of amino-oxyacetic acid were dissolved in 50 ml of 90% ethanol. The solution was mixed with 7.4 g of sodium acetate and then refluxed for 20 minutes. The reaction mixture was subsequently concentrated by evaporation in a vacuum. After an excess of 2 N sodium hydroxide had been added, the residue was twice extracted with ether, after which the remaining aqueous solution was acidified with 2 N hydrochloric acid and again extracted twice with ether. The latter ethereal solution was washed twice with water, then dried over anhydrous sodium sulfate and subsequently concentrated by evaporation. The residue was crystallized from a mixture of ether and petroleum ether, them from highly dilute ethanol and ultrimately twice from a mixture of benzene and petroleum ether. The substance obtained melted at 121° C.-123° C.
