Procedure
At room temperature, 250 mg (0.83 mmol) of methyl 5-bromo-2-oxo-6-(trifluoromethyl)-1,2-dihydropyridine-3-carboxylate were stirred in 5 ml of allylamine for 18 h. By addition of 2N hydrochloric acid, the pH was then adjusted to 2, resulting in the precipitation of a colorless solid. Filtration with suction and drying gave 134 mg (50% of theory) of the product.
