실험 절차
A mixture of ethyl 1-isopropyl-6-methyl-2-oxo-1,2-dihydropyridine-3-carboxylate as prepared in Example 1(5) (1.12 g, 5.00 mmol) and N-bromosuccinimide (890 mg, 5.00 mmol) in N,N-dimethylformamide (10 mL) was stirred at room temperature for 16 h, and then the solvent was removed in vacuo. The residue was chromatographed on a column of silica gel eluting with n-hexane/ethyl acetate (v/v=2/1˜1/1) to give 1.34 g (91%) of the title compound as a yellow solid.
