Triethylenetetramine → 1,8-Bis[beta-(3,5-di-t-butyl-4-hydroxy phenyl) propionamido]-3,6-diazaoctane

Participants

Reaction Steps

0.02 moles β-(3,5-di-t-butyl-4-hydroxy phenyl) propionyl chloride in 25 ml methylene chloride was added to a stirred mixture containing a solution of 0.02 mol triethylene tetramine in 125 ml methylene chloride and 25 ml 10% sodium carbonate. The mixture was stirred for two hours and then separated. The methylene chloride layer was washed with 5% sodium carbonate solution and then with water, subsequently dried over anhydrous magnesium sulfate and finally evaporated to dryness. A resinous material of 1,8-bis[β-(3,5-di-t-butyl-4-hydroxy phenyl) propionamido]-3,6-diazaoctane resulted which was pulverized to give a light brown solid having a melting point of 80°-110° C.
