Conditions

Temperature
120 °C

Procedure

500 mg of dimethyl 5-bromo-pyridine-2,4-dicarboxylate (from Example 3) are dissolved in 10 ml of toluene. 0.26 ml of phenylpropylamine are added dropwise and the mixture is stirred at 120° C. for 10 hours. After cooling, the solvent is evaporated off, the residue is taken up in ethyl acetate and the organic phase is washed with 2 portions each of citric acid, sodium bicarbonate solution and water. After drying over magnesium sulfate, the solvent is evaporated. Chromatography on silica gel gives 117 mg of product with a melting point of 102°-104° C.
