21043-40-3, 1-Cyclopentylpiperazine is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
1-cyclopentyl Piperazine(507 mg, 0.003 mmol) was added to a stirred solution of 6 (1 g, 0.0029 mmol) in dry 1,4-Dioxaneand DIPEA (0.7 mL,0.005 mmol). The solution was stirred for 4 h at room temperature. After adding water a precipitate was formed which was filtered to give compound 7 (1.1g, 86% yield) as white solid (m.p-156-159 C).1H NMR (300 MHz, CDCl3) ^ 1.39 – 1.50 (m, 2H), 1.58 (dd, J=7.72, 4.71 Hz, 2H), 1.68 – 1.75 (m, 2H), 1.88 (br. s, 2H), 2.51 – 2.60 (m, 1H), 2.64 – 2.70 (m, 4H), 3.66 – 3.71 (m, 1H), 3.76 – 3.82 (m, 4H), 3.96 (s, 3H), 5.25 (s, 2H), 7.06 (s, 1H), 7.18 (s, 1H), 7.31 – 7.41 (m, 3H), 7.42 – 7.48 (m, 2H).ESI [M+H]+:453.40., 21043-40-3
21043-40-3 1-Cyclopentylpiperazine 806421, apiperazines compound, is more and more widely used in various fields.
