Reaction Steps

At room temperature, 0.36 g (2.04 mmol) of N-bromosuccinimide was added to a suspension of 0.3 g (1.36 mmol) of methyl 2-oxo-6-(trifluoromethyl)-1,2-dihydropyridine-3-carboxylate in 10 ml of glacial acetic acid, and the mixture was then heated under reflux for 2 days. The reaction mixture was then added to water and extracted with dichloromethane. The extract was concentrated, and the residue was purified further by preparative HPLC. This gave 227 mg (56% of theory) of a colorless powder.
