Participants

Reaction Steps

N6-(2-{[7-(2,4-Dichlorophenyl)imidazo[1,2-c]pyrimidin-5-yl]amino}propyl)-3-nitropyridine-2,6-diamine (Example 83) is prepared in analogy to Example 82 from Example 37A (300 mg, 0.47 mmol), 2-amino-6-chloro-3-nitropyridine (161 mg, 0.93 mmol) and N,N-diisopropylethylamine (600 mg, 4.6 mmol). The crude product is reprecipitated from N,N-dimethylformamide and acetonitrile. The product is filtered off and washed with acetonitrile and dried. 99 mg (45% of theory) of the product are obtained as a solid.
