A microwave reaction flask was charged with 4-bromo-2-(5-cyclopropylcarbamoyl-2-methyl-phenylamino)-thiazole-5-carboxylic acid benzylamide (10 mg, 0.02 mmol, 1.0 eq), 3-methyl-4-fluorophenylboronic acid (32 mg, 0.21 mmol, 10 eq), tetrakistriphenylphosphine palladium (5 mg, 0.004 mmol, 0.2 eq), 200 μL of dioxane, and 200 μL of saturated aqueous K2CO3. The mixture was heated with stirring in the microwave at 120° C. for 10 minutes. The layers were separated and dioxane layer was concentrated and purified by preparative HPLC. Fractions containing product were concentrated to provide the title compound as a white solid (7.5 mg, 71%). HPLC (4 minutes gradient) tR 2.61 min; MS m/z 515.24 [M+H]+; 1H NMR (DMSO-d6, 500 MHz) δ 0.53 (m, 2H), 0.66 (m, 2H), 2.16 (s, 3H), 2.29 (s, 3H), 2.82 (m, 1H), 4.29 (d, J=4.3, 2H), 7.05 (t, J=8.9, 1H), 7.20-7.30 (m, 6H), 7.44-7.51 (m, 3H), 8.30-8.36 (m, 3H), 9.72 (s, 1H) ppm.
