Reaction Steps

To a solution of (4-{4-[(−)-3-[(E)-hydroxyimino]-3-(2-methyl-pyridin-4-yl)-1-o-tolyl-propyl]-phenyl}-[1,2,3]triazol-1-yl)-acetic acid ethyl ester (35 mg) in a mixture of dioxane (1 mL) and water (1 mL) was added lithium hydroxide (14 mg) and the reaction mixture heated by microwave irradiation to 120° C. for 20 min. The solution was adjusted to approximately pH 3 by using 1 M aqueous hydrochloric acid and then extracted over a sat. solution of brine (50 mL) with ethyl acetate (3×50 mL). The combined organic phases were dried over sodium sulfate and the crude reaction product purified by silica gel chromatography using a MPLC system (CombiFlash Companion, Isco Inc.) eluting with a gradient of dichloromethane/methanol (100:0 to 90:10). Light yellow solid. MS (ESI−): m/z=454.1 ([M−H]−).
