実験手順

In a round-bottomed flask, (R)-N-[5-(1-hydroxy-2-{2-[4-(2-methyl-thiazol-4-yl)-phenoxy]-ethylamino}-ethyl)-pyridin-2-yl]-acetamide (74 mg, 0.18 mmol) was dissolved in 1.0 mL of ethanol, and 1.0 mL of 2 M sodium hydroxide was added to the solution. The reaction mixture was then heated to about 80° C. for about twenty minutes, and was then diluted with water and adjusted to about pH 11. The aqueous phase was extracted with four portions of methylene chloride, and the combined organic extracts were dried over magnesium sulfate, filtered, and concentrated in vacuo. The resulting crude material was purified by column chromatography (methylene chloride to 20% methanol/methylene chloride) to afford 49 mg (74%) of the desired product. LRMS ([M+1]+): 371.2.
