Abstract:4-Methyl-2-nitroaniline was used as raw material, which reacted with 1-bromo-3-phenylpropane (3) to obtained 4-methyl-2-nitro-N-(3-phenyl-propyl)-aniline (2) under the catalysis of sodium hydride. The nitro group of 3 was reduced by iron powder toproduce the compound 4-methyl-N1-(3-phenyl-propyl)-benzene-1,2-diamine (1). The structure of the product 4 was confirmed by 1H NMR. Meanwhile, the reaction conditions were optimized: in the first step reaction, sodium hydride as catalyst, toluene as solvent, n(4-methyl-2-nitroaniline)∶n(sodium hydride)=1∶2, reaction at 70 ℃ for 24 h; in the reduction reaction: iron powder and ammonium chloride as reducing agent, n(iron powder)∶n(ammonium chloride)=1∶2, n(4-methyl-2-nitro-N-(3-phenyl propyl)-anilin∶n(ironpowder)=1∶2. Under optimal conditions, the total of 4-methyl-N1-(3-phenyl-propyl)-benzene-1,2-diamine(1) was 59.7%. Moreover, the preliminary biological results showed that 4-methyl-N1-(3-phenyl-propyl)-benzene-1,2-diamine (1) showed obvious antiproliferative effect on MCF-7, MDA-MB-231, HepG2, PC-3and A549 cell lines, especially to MDA-MB-231, which showed strong inhibitory effect with the IC50 value was (7.9±0.9) μmol·L-1.
