Triethylamine → HCID 19091887, compound

Participants

Reaction Steps

A solution of 1.9 g (4.78 mmol) of 3-(octadecyloxy)phenylacetic acid in 40 ml of thionyl chloride was refluxed for 1.5 hours. The excess thionyl chloride was removed at reduced pressure and the resultant acid chloride was dissolved in 40 ml of anhydrous methylene chloride. This solution was added dropwise to an ice bath cooled mixture of 1.0 g (6 mmol) of dimethyl iminodiacetate and 1.4 ml (10 mmol) of triethylamine in 25 ml of methylene chloride. The reaction mixture was kept at room temperature for 17 hours and then was washed with 1N HCl, dried and concentrated to a solid. Purification by chromatography on 150 g of silica gel using 40% ethyl acetate-hexane gave 1.7 g (65% yield, mp 52°-55°) of N-(2-methoxy-2-oxoethyl)-N-[3-(octadecyloxy)phenylacetyl]glycine methyl ester.
