Procedure

To a mixture of 4-aminopyrido[2,3-d]pyrimidin-5(8H)-one (11.5 mg, 0.0708 mmol), cesium carbonate (34 mg, 0.10 mmol) and potassium iodide (1.2 mg, 0.0071 mmol) in N,N-dimethylformamide (0.2 mL) was added benzyl 3-[3-chloro-5-(1-chloroethyl)-6-ethoxy-2-methylphenyl]azetidine-1-carboxylate (30 mg, 0.07 mmol). The mixture was stirred at 140° C. for 1 hour, cooled and then diluted with water, extracted with ether. The combined organic layers were dried over MgSO4 and concentrated to afford the crude product which was used in the next step directly. LCMS calculated for C29H31ClN5O4 (M+H)+: m/z=548.2; Found: 548.2.
