Versuchsvorschrift
6-Methoxycarbonylmethylsulfanyl-5-nitro-nicotinic acid methyl ester (1.0 g) in acetic acid (50 mL) was treated with iron powder (10 g) and the mixture was stirred and heated at 60° C. for 1 hour, cooled and filtered. The filtrate was evaporated, treated with sodium bicarbonate solution and extracted with warm chloroform. It was dried (anhydrous sodium sulfate) and evaporated to give a white solid (0.85 g).
