21655-48-1, cis-2,6-Dimethylpiperazine is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
21655-48-1, (2S,6R)-2,6-dimethylpiperazine (6.85 g, 60.00 mmol) was added to ethyl 4-fluorobenzoate (2.201 mL, 15 mmol), in DMSO (40 mL) warmed to 120 C. under nitrogen. The resulting solution was stirred at 120 C. for 20 h. The reaction mixture was cooled and the solvent evaporated. The crude product was purified by silica column chromatography, eluting with a gradient of 0 to 10% methanol in dichloromethane containing 1% 880 ammonia. Pure fractions were evaporated to dryness to afford the desired compound (2.83 g, 71.9%) as a brown oil. 1H NMR (399.9 MHz, CDCl3) delta 1.15 (6H, d), 1.37 (3H, t), 2.38 (1H, d), 2.41 (1H, d), 2.96-3.04 (2H, m), 3.65-3.69 (2H, m), 4.33 (2H, q), 6.84-6.87 (2H, m), 7.89-7.93 (2H, m). MS: m/z 263 (MH+).
The synthetic route of 21655-48-1 has been constantly updated, and we look forward to future research findings.
