Procedure

To a solution (40 mL) of 5-methyl-4H-1,2,4-triazol-3-amine (2.5 g) and 1-methoxypropan-2-one (2.7 g) in acetic acid was added sodium cyanoborohydride (8.1 g), and the mixture was stirred at room temperature for 16 hr. Water was added to the reaction mixture, and the solvent was evaporated under reduced pressure. The obtained residue was poured into saturated aqueous sodium hydrogen carbonate, and the mixture was extracted with a mixed solvent of ethyl acetate and isopropyl alcohol (3:1). The obtained extract was dried over anhydrous sodium sulfate, and the solvent was evaporated under reduced pressure to give the title compound as a colorless solid (1.4 g, 32%).
