Reaction Steps
Potassium cyanide (18 g) in water (150 ml) was added to a suspension of 2'-benzoyl-2,2,4'-trichloro-acetanilide (30 g) in ethanol (400 ml). The reaction was stirred overnight and after treatment with charcoal diluted with water, 2-Amino-5-chloro-3-phenyl-3H-indol-3-ol (19.57 g) was obtained as off white crystals m.p. 205°-208°C after recrystallization from acetonitrile.
