실험 절차

4,4-Dimethyl-7-nitro-1,2,3,4-tetrahydroquinoline (1.08 g) was heated at reflux in 10 ml of acetic anhydride for 2 h, cooled to RT, diluted with water (100 ml), neutralized to pH7 with NaHCO3 (solid) and extracted with EtOAc. The organic portion was washed with brine, removal of the solvents afforded 1-(4,4-dimethyl-7-nitro-3,4-dihydroquinolin-1(2H)-yl)ethanone as a solid.
