Versuchsvorschrift

2.3 g (0.1 mol) of sodium were added in portions to a suspension of 5 g (0.014 mol) of 2-benzylthio-1-(2,6-diethylphenyl)-imidazole-5-carboxylic acid in 50 ml of liquid ammonia at -40° to -50° C. After 1 hour, 6 g of ammonium chloride were added at the same temperature, and the mixture was allowed to warm up to room temperature overnight. The residue was taken up in 200 ml of water, and the solution was acidified to pH 3 with semiconcentrated hydrochloric acid and filtered under suction. 3.0 g (79% of theory) of 1-(2,6-diethylphenyl)-2-mercaptoimidazole-5-carboxylic acid, a solid having a melting point above 230° C., were obtained.
