Reaction Steps
Analogously to Example 1, 6.8 g. (38 mmole) 6-amino-3,3-dimethylindolin-2-one are diazotised and reduced. Into the solution are added dropwise 10.9 g. (85 mmole) 2-acetylthiophene and the oil which separates out is taken up in methylene chloride, dried and evaporated. As crude product, there are obtained 11.2 g. 2-acetylthiophene-(3,3-dimethyl-2-oxoindoline-6-hydrazone) which is further reacted without purification.
