실험 절차

A solution of 6-chloro-5-iodopyrazin-2-amine (step 1) (13.74 g, 53.8 mmol) in dioxane (300 ml) was degassed with N2 and treated with p-tolylboronic acid (17.55 g, 129 mmol), K2CO3 (22.30 g, 161 mmol) and PdCl2(dppf)-CH2Cl2-adduct (4.39 g, 5.38 mmol). The orange suspension was stirred at 110° C. for 2 days. After cooling to room temperature the reaction mixture was concentrated under reduced pressure. The crude mixture was absorbed onto silica and purification by chromatography eluting with 0-60% EtOAc in iso-hexane afforded the titled compound as a beige coloured solid;
