実験手順

A suspension of 0.426 g of 1-amino-6-methyl-5-nitro-2-anthraquinonecarboxylic acid p-heptylphenyl ester, 50 ml of toluene, 50 ml of ethanol and 0.10 g of palladium/barium carbonate catalyst poisoned with 2 wt.% lead was hydrogenated at room temperature until the hydrogen uptake came to a standstill. The mixture was filtered. The filtrate was concentrated in vacuo and the residue was purified by chromatography on silica gel with methylene chloride as the eluent. Recrystallization from methylene chloride/hexane, yielded 0.334 of 1,5-diamino-6-methyl-2-anthraquinonecarboxylic acid p-heptylphenyl ester as violet crystals; m.p. (C-N) 163.7°-165.7° C., cl.p. (N-I) 190.9°-191.4° C., nematic; E277 =15280, E524 =14700.
