Participants

Reaction Steps

A mixture of 1-bromo-3,5-dimethoxybenzene (436 mg, 2.01 mmol), 2-chloro-5-methyl-pyrimidin-4-ylamine (287 mg, 2.00 mmol), Pd(OAc)2 (44 mg, 0.20 mmol), Xantphos (237 mg, 0.41 mmol) and potassium tert-butoxide (448 mg, 3.99 mmol) in dioxane (15 mL) and DMF (5 mL) was microwaved at 160° C. for 20 min. The reaction mixture was cooled to room temperature and filtered rinsing with DCM and methanol. The filtrate was concentrated and purified using gradient flash chromatography (0-100% ethyl acetate in hexanes) to afford the title compound as a yellow solid (182 mg, 33%).
