preparation Embodiment 1
[0024] Phylloline (2mmol) and N-tert-butoxycarbonyl-homopiperazine (2mmol) were dissolved in 10mL of anhydrous toluene, refluxed at 110°C until the end of the reaction, and the solvent was recovered under reduced pressure to prepare a crude product, which was subjected to silica gel column chromatography Purification (diethylamine / methanol / chloroform=2 / 4 / 94) gave the target compound (1).
[0025] Compound 1 structure determination data:
[0026] N-tert-butoxycarbonyl-N-homopiperazinyl-3-indolylmethylamine (N-tert-Butyloxycarbonyl-N-homopiperazinyl-3-indolymethylamine, 1): yellow powder, yield 82%. 1 H NMR (400MHz, CDCl 3 )δ H : 8.91(s, 1H, NH), 7.76-7.03(m, 5H, H-2, 4, 5, 6, 7), 3.83(s, 2H, CH 2 N), 3.55-3.43(m, 4H, H-2', 4'), 2.72-2.66(m, 4H, H-6', 7'), 1.85-1.82(m, 2H, H-3'), 1.49(s, 9H, Me-Boc). 13 C NMR (100MHz, CDCl 3 )δ: 155.7(s, C-8), 136.4(s, C-8), 127.9(s, C-9), 123.8(d, C-2), 121.8(d, C-6), 119.5( d, C-5), 119.3 (d, C-4), 112.8 (s, C-3), 111.2 (d, C-7), 79.4 ...
preparation Embodiment 2
[0028] Phylloline (4mmol), dissolved in 10mL of anhydrous toluene with 2-aminoethylpiperazine (2mmol), refluxed at 110°C until the end of the reaction, recovered the solvent under reduced pressure, prepared a crude product, and performed silica gel column chromatography ( Diethylamine / methanol / chloroform=3 / 5 / 92) to obtain the target compound (2).
[0029] Compound 2 structure determination data:
[0030] N-(N-3-indolylmethylaminoethyl)-N-piperazinyl-3-indolylmethylamine[N-[N-(3-indolymethyl)-aminoethyl]-N-Piperazinyl-3-indolylmethylamine , 2]: white powder, yield 70%. 1 H NMR (CDCl 3 , 400MH Z )δ H : 8.72(s, 2H, NH), 7.72-7.01 (m, 10H, H-2, 2', 4, 4', 5, 5', 6, 6', 7, 7'), 3.98(s, 2H, CH 2 N), 3.72(s, 2H, CH 2 CH 2 NH CH 2 ), 3.45 (s, 1H, CH 2 CH 2 NH CH 2 ), 2.79-2.77 (m, 2H, CH 2 CH 2 NHCH 2 ), 2.69-2.68 (m, 2H, CH 2 CH 2 NHCH 2 ), 2.52-2.42(m, 4H, H-3', 5'), 2.20-2.18(m, 4H, H-2', 6'). 13 C NMR (100MHz, CDCl 3 )δ: 136.4 (s, C-8, 8′), 128.1 (s, C-...
preparation Embodiment 1
