Thyroxine methyl ester (5 g), as prepared above, N-carbobenzoxyglycylglycine (1.67 g) and cyclohexylmorpholinoethylcarbodiimide (5.3 g) were combined in 40 ml of dimethylacetamide. The mixture was stirred at room temperature for 24 hours, poured into deionized water, and the resulting residue collected and washed with water. The residue was recrystallized from methanol and water, yielding the product, N-carbobenzoxyglycylglycylthyroxine methyl ester.
