Versuchsvorschrift
Potassium t-butoxide (1.63 g, 14.5 mmoles) and 5 ml absolute ethanol were heated to 80°. 1-Phenyl-2(1H, 3H)-indolone 2.09 g, 10 mmoles) was added, followed by ethyl formate (1.09 ml, 13.5 mmoles). The mixture was heated 5 minutes, cooled to 25°, and the nearly solid mass diluted with 50 ml H2O and crushed ice, acidified to pH 3 with 3N HCl and title product recovered by filtration, 2.2 g, m.p. 192°-195°; m/e 237. cf J. Prakt. Chem. 135:345-360 (1932); J. Med. Chem. 8:637 (1965).
