Procedure

2-((tert-butoxy)carbonylamino)ethyl-3-((7-(3-(2-ethyl-4-(4-fluorophenyl)-5-(phenylmethoxy)phenoxy)propoxy)-8-propylchroman-2-yl)carbonylamino)propanoate (110 mg) was dissolved in methanol/chloroform (2:1, 5 mL) with 10% Pd/C (24 mg) and hydrogen gas bubbled in for 2 hours. The mixture was filtered through Celite®, rinsed with methanol, and concentrated under vacuum to afford 80 mg of 2-((tert-butoxy)carbonylamino)ethyl-3-((7-(3-(6-ethyl-4-(4-fluorophenyl)-3-hydroxyphenoxy)propoxy)-8-propylchroman-2-yl)carbonylamino)propanoate. Mass Spec (EI): 723.5 (M+H).
