Reaction Steps

0.7 g of 1-acetyl-3-(1-chloro-1-(4-(imidazol-1-yl-methyl)-phenyl)-methylene)-6-chloro-2-indolinone (educt X.1), 0.4 g of N-(dimethylamino-methylcarbonyl)-N-methyl-p-phenylenediamine (educt XV.125) and 1.2 ml of triethylamine are dissolved in 10 ml of dimethylformamide and stirred for 15 hours at 60° C. After cooling, 10 ml of methanol and 2 ml concentrated ammonia are added and the mixture is stirred for a further three hours at ambient temperature. Water is added and the mixture is extracted with ethyl acetate. The organic phase is washed three times with water, dried over sodium sulphate and concentrated in the rotary evaporator. The residue is purified through a silica gel column with methylene chloride/methanol/ammonia 10:1:0.1 as eluant.
