Reaction Steps

A mixture of 3-(5-tert-butoxycarbonylpyrid-2-yl)-5-(3-cyanophenyl)-1,2,4-oxadiazole (114 mg, 0.33 mmol) in formic acid (98%, 6 mL) was heated for 2 days at 45° C. The incomplete reaction was resubjected to additional formic acid (96%, 6 mL) for 1 day at 45° C. Co-evaporation of the solvent in vacuo using toluene afforded 103.6 mg of 3-(5-hydroxycarbonylpyrid-2-yl)-5-(3-cyanophenyl)-1,2,4-oxadiazole, as a white solid.
