4-Chloro-8-(2,6-difluorophenyl)-2-{[2-hydroxy-1-(hydroxymethyl)ethyl]-amino}pyrido[2,3-d]pyrimidin-7(8H)-one (0.056 g, 0.17 mmol), N-cyclopropyl-3-fluoro-4-methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzamide (0.065 g, 0.17 mmol), K2CO3 (0.07 g, 0.51 mmol) and tetrakis triphenyl phosphine palladium (10 mg, 0.05 eq) are dissolved in dioxane/water (3:1, 10 mL) and heated to about 100° C. for about 3 h. The mixture is concentrated and purified via reverse phase HPLC to afford the title compound (9 mg, yellow powder, mp 214.2-217.5): LC-MS m/z 540 (M+H)+, 1.69 min (ret time). HPLC indicates 96% pure.
