実験手順

A mixture of 5-bromo-1-cyclohexylmethyl-2-methyl-6-oxo-1,6-dihydro-pyridine-3-carboxylic acid methyl ester (4.95 g, 14.5 mmol), N-bromosuccinimide (2.83 g, 15.9 mmol), and benzoyl peroxide (0.35 g, 1.45 mmol) in CCl4 (140 mL) was refluxed for 16 h. The solvent was evaporated in vacuo, and the residue was chromatographed (10% EtOAc/hexanes) to give 4.49 g of the title compound as a white solid. MS: (+) m/z 422.09 (M+1).
