Uses
N1-?[2-?(Dimethylamino)?ethyl]?-?5-?methoxy-?N1-?methyl-?N4-?[4-?(1-?methyl-?1H-?indol-?3-?yl)?-?2-?pyrimidinyl]?-?1,?2,?4-?benzenetriamine can be involved as reactant/reagent in "Schizophrenic" self-assembly of dual thermoresponsive block copolymers bearing a zwitterionic and a non-ionic hydrophilic block.
Synthesis
Under nitrogen protection, 28.5 g (0.060 mol) of N1-(2-(dimethylamino)ethyl)-5-methoxy-N1-methyl-N4-(4-(1-methyl-1H-indol-3-yl)pyrimidin-2-yl)-2-nitrobenzene-1,4-diamine was added to 500 mL of methanol with 2.5 g of palladium carbon catalyst. The reaction was stirred at 25 °C for 4 hours in a hydrogen atmosphere. Upon completion of the reaction, the catalyst was removed by filtration and the filtrate was concentrated to dryness under reduced pressure to afford 26 g of the brown solid product N1-[2-(dimethylamino)ethyl]-5-methoxy-N1-methyl-N4-[4-(1-methyl-1H-indol-3-yl)-2-pyrimidinyl]-1,2,4-benzenetriamine in 97.3% yield.
