0.87 g (7.28 mmol) of N,N-dimethylformamide dimethyl acetal was added to 1.00 g (4.85 mmol) of 2-oxo-6-(trifluoromethyl)-1,2-dihydropyridine-3-carboxamide in 5 ml of toluene, and the mixture was heated under reflux for 4 h. After cooling, the resulting precipitate was filtered off with suction and dried: 0.5 g (39% of theory).
