2-(4-(benzyloxy)-1H-pyrazol-1-yl)ethanol (1.81 g, 8.3 mmol) was dissolved in THF (15 mL) under nitrogen. Pd/C (0.22 g, 0.21 mmol) was added and the solution was placed under vacuum and charged with a hydrogen balloon. The mixture stirred at ambient temperature overnight under this hydrogen atmosphere. The solution was filtered through GF/F paper and concentrated to give 1-(2-hydroxyethyl)-1H-pyrazol-4-ol (1.8 g, quantitative).
