Steps:
S.29.d Synthesis Example 29d
Synthesis Example 29d 8-Acetoxy-5,6,7,8-tetrahydroquinoline 5,6,7,8-Tetrahydroquinoline N-oxide (1.6 g, 11 mmol) was mixed with acetic anhydride (9.2 ml) and stirred at 90° C. for 7 hours. After removing the solvent by evaporation under a reduced pressure, the residue was neutralized with sodium hydroxide aqueous solution (1 N) and the reaction product was extracted with chloroform. The extract was washed with saturated brine and dried with anhydrous sodium sulfate, and then the solvent was removed by evaporation under a reduced pressure and the thus obtained material was separated and purified by a silica gel column chromatography to obtain 690 mg (3.6 mmol, 33%) of the title compound. 1H-NMR (CDCl3): δ 1.80-2.00 (2H, m), 2.01-2.20 (5H, m), 2.71-2.81 (1H, m), 2.83-2.91 (1H, m), 5.98 (1H, t, J=4.6 Hz), 7.16 (1H, dd, J=4.7 Hz, 7.8 Hz), 7.45 (1H, d), 8.49 (1H, d); MW 191.23 (C11H13NO2); Mass spectrum TSP m/z 192 (M+H)+.
