実験手順

To a mixture of 4-aminopyrido[2,3-d]pyrimidin-5(8H)-one (from VWR) (8.6 mg, 0.053 mmol), cesium carbonate (26 mg, 0.080 mmol) and potassium iodide (0.89 mg, 0.0053 mmol) in N,N-dimethylformamide (0.2 mL) was added tert-butyl 3-[3-chloro-5-(1-chloroethyl)-6-methoxy-2-methylphenyl]azetidine-1-carboxylate (20 mg, 0.05 mmol, from Example 1, step 5, racemic intermediate). The mixture was stirred at 140° C. for 1 hour, then cooled and was diluted with water, extracted with ether. The organic layers were dried over MgSO4 and concentrated to afford the crude product which was used in the next step directly. LCMS calculated for C25H31ClN5O4 (M+H)+: m/z=500.2; Found: 500.1.
