実験手順
To a stirred solution of 15 g (0.93 mol) of 4,4-dimethyl-1,2,3,4-tetrahydroquinoline in 50 ml of pryidine, at 0° C., was added, dropwise, 14.5 g (0.185 mol) of acetyl chloride over a 30 minute period. Stirring was continued at 0° C. for 1 hour, and then the reaction mixture was poured onto 200 g of ice. The resulting mixture was extracted with ether. The combined organic extracts were washed successively with 1N hydrochloric acid and saturated sodium bicarbonate and then they were dried using magnesium sulfate. Evaporation of the ether solution in vacuo afforded 18.8 g (99% yield) of the title compound as a yellow oil.
