Participants

Reaction Steps

Ethyl {[4-(3-{[benzyl(isopropyl)amino]methyl}-4-hydroxyphenoxy)-3,5-dimethylphenyl]amino}(oxo)acetate (50 mg, 0,10 mmol) and NaOH (40 mg, 1.02 mmol) are dissolved in dioxane/water (0.5 1, 1:1 v/v) and stirred at room temperature for 1 h. The reaction mixture is partitioned between ethyl acetate and potassium dihydrogen phosphate/disodium hydrogen phosphate buffer solution (pH 7), and the organic phase is salted out with NaCl, filtered and evaporated. The resulting crude product is purified by preparative RP-HPLC with a water/acetonitrile/TFA eluent.
