To a solution of methyl 1-(4-methoxy-1H-pyrrolo[2,3-c]pyridin-7-yl)-1H-1,2,4-triazole-3-carboxylate (220 mg, 0.805 mmol) in THF (20 mL) was added LiAlH4 (1.208 mL, 2.415 mmol) dropwise over 5 min period at room temperature. The solution was refluxed for 1H and then cooled in an ice bath. The reaction mixture was quenched with water and extracted with EtOAc (3×100 ml). The organic layers were combined, washed with brine (30 ml), dried under MgSO4 and concentrated. The residue was purified by prep. HPLC to give (1-(4-methoxy-1H-pyrrolo[2,3-c]pyridin-7-yl)-1H-1,2,4-triazol-3-yl)methanol (100 mg, 0.408 mmol, 50.6% yield).
