Participants

Reaction Steps

The title compound was prepared in accordance with the general method of Example 108(C), from 2-bromo-6-(fluoromethyl)-pyridine (43 mg, 0.22 mmol) and 2-but-3-ynyl-6-fluoro-quinoxaline (45 mg, 0.22 mmol). Microwave conditions: 120° C. for 15 minutes. The crude residue was purified by flash chromatography (cyclohexane/AcOEt 3:2) to yield 45 mg (0.15 mmol, 65%) of 6-fluoro-2-(4-(6-(fluoromethyl)pyridin-2-yl)but-3-ynyl)quinoxaline as an orange solid with a purity of 85%.
