실험 절차
To a suspension of 6-chloromethyluracil (163 g) in acetic acid (500 ml), sulfuryl chloride (120 ml) was added dropwise at room temperature over 20 minutes, followed by stirring at the same temperature for 3 hours. The reaction mixture was poured into ice water (500 ml), and a crystallized matter was collected by filtration, whereby 182.3 g of the title compound were obtained (yield: 92%).
