Versuchsvorschrift
Sulfuryl chloride (120 ml) was added dropwise to a suspension of 6-chloromethyluracil (163 g) in acetic acid (500 ml) over 20 minutes at room temperature, and the mixture was stirred for an additional 3 hours at room temperature. The resultant solution was poured into iced water (500 ml), and then precipitated crystals were collected through filtration, to there by obtain 182.3 g of 5-chloro-6-chloromethyluracil (92% yield).
