الإجراء التجريبي

To a solution of methyl 2-[6-(methyloxy)-1,5-naphthyridin-4-yl]-2-propenoate (2.53 g, 10.37 mmol) in DMF (4 ml) and tetramethylguanidine (0.1 ml) was added 1,1-dimethylethyl 4-piperidinylcarbamate (2.08 g, 10.37 mmol). The reaction was stirred for 1 hour at 70° C. after which time the solvent was evaporated. The residue was chromatographed on silica eluting with a gradient of 5% methanol in dichloromethane affording the desired compound as a yellow solid (2.66 g, 58%).
