Reaction Steps
30.0 g (0.137 mol) of 1-acetyl-5-nitro-2-indolinone are dissolved in 200 ml of acetic anhydride and after the addition of 50.0 g (0.274 mol) of trimethyl orthobenzoate stirred for 3 hours at 100° C. After cooling it is evaporated down to half the quantity, diluted with ether/petroleum ether, the precipitate is suction filtered and dried.
