Versuchsvorschrift

A solution of 5 g 5-Methyl-3H-imidazole-4-carboxylic acid ethyl ester and 7.2 g NIS in 50 ml THF were refluxed for 10 h. After cooling, the solvent was removed under reduced pressure and the residue taken-up in ethyl acetate, washed with sat. NaS2O3 solution and dried over MgSO4. After removal of the solvent under reduced pressure the product was purified by recrystallisation from ethyl acetate. Yield: 7 g
