実験手順
A solution of 5,6-di-p-tolylpyrazin-2-amine (step 2) (4.94 g, 17.94 mmol) in DMSO (40 ml), was treated with N-bromosuccinimide (3.19 g, 17.94 mmol). The reaction mixture was stirred at room temperature for 2 hours to give a beige coloured suspension. The suspension was diluted with water (700 ml) and the pH was adjusted to pH 8-9 using a sat. NaHCO3 solution. The suspension was filtered, washed with water (×3) and dried under vacuum to afford the titled compound as a beige coloured solid;
