6531-38-0, 2,2′-(Piperazine-1,4-diyl)diethanamine is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
6531-38-0, To the MeOH solution of 2-[4-(2-amino-ethyl)-piperazine-1-yl]-ethylamine (0.344 g, 2 mmol), salicylaldehyde (0.484 g, 4 mmol) was added under ice-cold condition and stirred for 3 h to give a yellow solid which was separated by filtration through G4 sintered bed and washed thoroughly with ice cold MeOH. The isolated solid was next dried in vacuo over anhydrous CaCl2. The single crystals uitable for X-ray analysis were obtained from hot MeOH after 4 days and found to be same as reported earlier [21]. Yield 1.92 g (~87% yield), mp 152 C. Selected IR peaks (KBr, cm-1, vs = very strong, br = broad, s = strong, m = medium): 2939(b), 2823(b), 1641(vs), 1499(s), 1441(s), 1281(vs), 1159(s), 1017(s), 863(s), 764(s). 1H NMR (CDCl3, ppm): delta (phenolic OH) 13.43(s, 2H); 8.35 (s, 2H); 7.35-6.83(m, 8H); 3.73(t, 4H); 2.70(t, 4H); 2.57 (s, 8H). 13C NMR (CDCl3, ppm): delta (C7,16) 165.52; (C1,22) 161.16; (C6,17) 132.13; (C3,5, 18,20)131.14; (C4,19) 118.44; (C2,21) 116.98; (C9,14) 58.59; (C8,15) 56.98; (C10,11,12,13) 53.33.
As the paragraph descriping shows that 6531-38-0 is playing an increasingly important role.
