실험 절차

Bromine (170 μl, 3.30 mmol) was added dropwise to a solution of 5H-6-thia-4,5-diaza-chrysene 6,6-dioxide 184 (467 mg, 1.65 mmol) in 1,4-dioxane/chloroform (1:1, 124 ml) at 0° C. After 2 h, chloroform (30 ml) was added and the resulting precipitate was collected by filtration. The solid was triturated from MeOH to give the title compound (385 mg, 64%).
