Participants

Reaction Steps

Prepared from 4-(4-dimethylaminophenylamino)-6-nitroquinoline-3-carbonitrile (5.00 g), 1.20 g of anhyd hydrazine and 0.500 g of 10% Pd/C in the same manner as EXAMPLE 388 155179. After washing first with MeOH (discarded), the product was eluted with DMF. The latter solvent was collected separately, evaporated and the residue was dried in vacuo (50° C.). The yield of 6-amino-4-(4-dimethylaminophenylamino)quinoline-3-carbonitrile was 4.00 g as a yellow solid: mass spectrum (electrospray, m/e): M+H 303.9.
