Versuchsvorschrift
To a stirred solution of 70 g (0.64 mol) 4-hydroxy-6-methylpyrimidine in acetic acid is added 127 g (0.56 mol) NIS portion wise at RT within 15 min. The reaction is stirred for 30 h at RT until all starting material is consumed. The reaction mixture is diluted with water and the solid product is filtered off and washed with sodium thiosulfate solution to remove excess iodine. After drying, the desired product is obtained as a pale brown solid (90 g; 60%) which is used without further purification.
