Participants

Reaction Steps

Add 2 N sodium hydroxide (20 mL) to a solution of 5-[3-(2-methoxyphenyl)-[1,2,4]oxadiazol-5-yl]pentanoic acid methyl ester (4.00 g, 13 mmol) in methanol (100 mL) at room temperature under nitrogen and stir the mixture for 3 hours. Remove the solvent under reduced pressure, dilute the residue with water (200 mL) and wash with diethyl ether (200 mL). Adjust the aqueous layer to pH 1 with 2 N HCl and collect the solids by vacuum filtration to afford 5-[3-(2-methoxyphenyl)-[1,2,4]oxadiazol-5-yl]pentanoic acid (3.65 g, 99%). APCI mass spectrum m/z 275 [C14H16N2O4−H]−.
