Procedure

A mixture of 1-benzyl-N-(tetrahydro-2H-pyran-4-yl)-1H-1,2,3-triazol-5-amine (450 mg), 10% palladium-carbon (containing water by 50%, 450 mg), ammonium formate (631 mg), acetic acid (1.2 mL) and methanol (12 mL) was stirred at 60° C. for 16 hr under a nitrogen atmosphere. The reaction mixture was filtered, and the solvent was evaporated. The residue was diluted with saturated aqueous sodium hydrogen carbonate solution, and the mixture was extracted with ethyl acetate-isopropyl alcohol (3:1). The extract was washed with saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure to give the title compound as a white powder (209 mg, 73%).
