실험 절차

5 g (28.2 mmol) of 6-methoxyisatin, 4 ml (33.8 mmol) of acetophenone and 5.2 g (92.6 mmol) of potassium hydroxide were dissolved in 22.9 ml of abs. EtOH and the slurry heated at 80° C. for 42 hours. After cooling of the reaction mixture, 50 ml of water were added and the solution extracted with 50 ml of Et2O. The ice-cooled aqueous phase was acidified to pH 1 with 37% HCl and the precipitate collected by filtration and washed with water.
