실험 절차

A solution of selenium dioxide (1.90 g) in 1,4-dioxan (5 ml) and water (1.2 ml) was added dropwise over 15 min to a stirred solution of 3-chloro-4-methylquinoline (2.91 g) in 1,4-dioxan (10 ml) at 60-70° C. The mixture was heated at reflux for 6 h, allowed to warm to room temperature, then concentrated in vacuo. The residue was purified by column chromatography (SiO2), eluting with dichloromethane to 5% methanol in dichloromethane by a stepwise gradient, to give the sub-title compound as a yellow solid (1.19 g).
