실험 절차

A suspension of 3-[4-chloro-6-(4-fluorophenyl)-2-(trifluoromethyl)pyrimidin-5-yl]benzenesulfonamide (0.15 g, 0.35 mmol), 4-hydroxy-N,3-dimethoxybenzamide (0.102 g, 0.52 mmol) and potassium carbonate (0.52 mmol) in acetonitrile (3 ml) were heated to reflux (65° C.) for 2 hours. Subsequently the reaction mixture was poured onto ice-cold water, extracted with dichloromethane (50 ml) and washed with brine. Evaporation of the organic layer furnished a crude material, which was purified by column chromatography; elution with 2% MeOH in dichloromethane furnished the required compound. 1H-NMR (DMSO-d6) δ: 3.73 (s, 3H), 3.79 (s, 3H), 7.16-7.20 (m, 2H), 7.37 (d, 1H), 7.41-7.45 (m, 5H), 7.53 (s, 1H), 7.62-7.63 (d, 2H), 7.85 (d, 1H), 7.89 (s, 1H). 11.9 (s, 1H); MS m/z: 593 (M++1).
