Procedure

The protected triazolone (4) (150 mg, 0.34 mmol) was dissolved in EtOAc (2 ml) and MeoH (2 mL) then palladium (100 mg, 10% on activated carbon) was added. The reaction was stirred under an atmosphere of hydrogen (balloon) at room temperature for 18 h. Filtration through a silcagel plug followed by removal of solvent under reduced pressure produced the desired product as a white solid (100 mg, 83%).
