Reaction Steps

1H-1,2,4-triazole (582 mg, 8.43 mmol), 2-chloro-3-nitrothiophene (1.15 g, 7.03 mmol) and potassium t-butoxide (944 mg, 8.43 mmol) were dissolved in DMF (30 mL). The resulting solution was stirred at 90° C. for 2 h, after which the reaction mixture was cooled to room temperature and diluted with Et2O. The solution was washed with brine and the organic phase was separated, dried (Na2SO4), filtered, concentrated under vacuum to give 1-(3-nitrothiophen-2-yl)-1H-1,2,4-triazole. Retention time (min)=1.073, method [1], MS (ESI) 197.0 (M+H).
