Hydrochloric Acid → HCID 66668795, compound

Participants

Reaction Steps

To a solution of (5-{4-[(−)-3-(2-methyl-pyridin-4-yl)-3-oxo-1-o-tolyl-propyl]-phenyl}-[1,3,4]oxadiazol-2-yl)-acetic acid ethyl ester (146 mg) in a mixture of ethanol (5 mL) and water (1.25 mL) was added sodium hydrogencarbonate (104 mg) and the reaction mixture stirred at room temperature for 4 h. 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=442.4 ([M+H]+).
