Reaction Steps

5-(3-((5-Bromopyrimidin-2-yl)oxy)-4-cyclobutyl-2-fluorophenyl)pyrazin-2-amine (60 mg, 0.14 mmol) and 5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyrimidin-2-amine (32 mg, 0.14 mmol) were added to a sealable microwave vial equipped with a stir-bar. 1,4-Dioxane (0.58 mL) and Na2CO3 (2 M, 0.14 mL) were added And the mixture sparged with Ar for 10 min before adding Pd(dppf)Cl2.CH2Cl2 (5 mg, 0.007 mmol) and heating the reaction mixture at 80° Celsius for 15 hours. The reaction was then cooled to rt, diluted with water (5 mL), and extracted with ethyl acetate (3×10 mL). The combined organic extracts were dried over Na2SO4, filtered, and concentrated to dryness. The crude product was purified by HPLC to give the title compound. MS (ESI): mass calcd. for C22H19FN8O, 430.17; m/z found, 431.1 [M+H]+. 1H NMR (500 MHz, CD3OD) δ 8.83 (s, 2H), 8.67 (s, 2H), 8.23 (s, 1H), 8.16 (s, 1H), 7.82-7.74 (m, 1H), 7.30 (d, J=8.3, 1H), 3.68 (p, J=8.9, 1H), 2.31-2.08 (m, 4H), 2.07-1.92 (m, 1H), 1.92-1.76 (m, 1H).
