Triethanolamine → HCID 54035976, compound

Participants

Reaction Steps

In the course of 10 minutes a solution of 3.45 ml of chloro-oxalic acid ethyl ester in 10 ml of methylene chloride is added dropwise to a solution of 9.2 g of 3-[3-(4-acetyl-3-methoxy-2-n-propylphenoxy)-propoxy]-aniline and 4.3 ml of triethanolamine in 90 ml of methylene chloride. After stirring for 5 hours at room temperature the mixture is poured onto water and extracted with methylene chloride. Concentration of the extracts by evaporation and recrystallisation of the residue from ether yields N-{3-[3-(4-acetyl-3-methoxy-2-n-propylphenoxy)-propoxy]-phenyl}-oxamic acid ethyl ester having a melting point of 91°-92°.
