To a mixture of 4-aminopyrido[2,3-d]pyrimidin-5(8H)-one (0.80 g, 4.9 mmol), cesium carbonate (2.4 g, 7.3 mmol) and potassium iodide (82 mg, 0.49 mmol) in N,N-dimethylformamide (20 mL) was added 3-bromo-1-chloro-5-(1-chloroethyl)-4-methoxy-2-methylbenzene (1.47 g, 4.93 mmol) and the mixture was stirred at 140° C. for 1 hour. The mixture was diluted with water and ethyl acetate. The precipitate was collected and dried to give the desired compound. LCMS calculated for C17H17BrClN4O2 (M+H)+: m/z=423.0; Found: 423.0.
