실험 절차

A 6 M solution of HCl in MeOH (8 mL; 4.8 mmol) was added to a suspension of O-(4-hydroxyphenyl)3,5-diiodo-L-tyrosine (2.12 g; 5 mmol) (prepared according to: Chalmers J. R., Dickson G. T., Elks J. and Hems D. A., “The Synthesis of Thyroxine and Related Substances”, Part V., J. Chem. Soc. (1949), 3424-3433) in MeOH (12 was stirred for 4 days at 20° C. Then a NaHCO3 saturated aqueous solution was added to the mixture until pH 7 was reached, obtaining a precipitate which was filtered by concentration of the solution a second crop of precipitate was obtained. The two samples were combined and dried (50° C.; 1.3 kPa) 3.7 mmol). Yield 87%.
