Procedure

A mixture of 3-(5-tert-butoxycarbonylpyrid-2-yl)-5-(3-cyano-5-fluorophenyl)-1,2,4-oxadiazole (69 mg, 0.19 mmol) in formic acid (98%, 3.5 mL) was heated at 40° C. for 17 hours. Evaporation of the solvent in vacuo afforded crude 3-(5-hydroxycarbonylpyrid-2-yl)-5-(3-cyano-5-flourophenyl)-1,2,4-oxadiazole as a white solid.
