2-mercapto-5-nitropyridine (5.0 g), 3-chloromethyl-4-propyl-4H-1,2,4-triazole hydrochloride (6.3 g) and potassium carbonate (11 g) was added to N,N-dimethylformamide (100 ml), and the mixture was stirred overnight at room temperature. The solvent was distilled off, and to the residue was added water, and the mixture was extracted with ethyl acetate. The organic layer was washed with water and saturated brine, and dried over anhydrous magnesium sulfate. The solvent was distilled off, to give 5-nitro-2-(4-propyl-4H-1,2,4-triazol-3-yl)methylthiopyridine (8.0 g) as brown crystals.
