실험 절차

A mixture of ethyl 1-isopropyl-6-methyl-2-oxo-1,2-dihydropyridine-3-carboxylate as prepared in 1(5) (3.0 g, 13.44 mmol) and N-chlorosuccinimide (1.79 g, 13.44 mmol) in N,N-dimethylformamide (27 mL) was stirred at room temperature for 16 h, and 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 3.19 g (92%) of the title compound as brown oil.
