실험 절차

Bromine (75.5 mg, 0.47 mmol) was added to a solution of 4-(1-methylimidazol-5-yl)-2-(4-sulphamoylanilino)pyrimidine (Example 15; 0.14 g, 0.42 mmol) and sodium acetate (41.7 mg, 0.51 mmol) in acetic acid (4 ml) and the mixture stirred for 1 hour. The volatiles were evaporated and the residue partitioned between EtOAc and saturated aqueous potassium hydrogen carbonate solution. The organic phase was separated and dried. The residue was pre-absorbed on to silica gel and purified by column chromatography on silica gel eluting with DCM/2% methanolic ammonia (9:1) to give the title compound (91 mg, 52%). NMR 10.14 (s, 1H), 8.75 (s, 1H), 7.90-7.69 (m, 4H), 7.17 (s, 2H), 3.84 (s, 3H); m/z 409.
