5308-25-8, 1-Ethylpiperazine is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
1-Ethylpiperazine (3.68 mL, 29.0 mmol) was added to methyl 4-fluorobenzoate (1.50 mL, 11.6 mmol) in dimethylsulfoxide (29.0 mL) at 25 C. The resulting solution was stirred at 120 C. for 18 h. The reaction mixture was concentrated and diluted with EtOAc (50 mL) and water (20 mL). NaOH (2N aqueous solution, 20 mL) was added and the layers were separated and washed with EtOAc (40 mL). The organic layers were combined and washed with water (40 mL) and saturated brine (40 mL). The organic layer was dried over magnesium sulphate, filtered and evaporated to afford the desired product (1.960 g, 68%). This was used without further purification. 1H NMR (399.9 MHz, CDCl3) delta 1.06 (3H, t), 2.40 (2H, q), 2.52 (4H, t), 3.29 (4H, t), 3.79 (3H, s), 6.78-6.81 (2H, m), 7.83-7.86 (2H, m). MS: m/z 249 (MH+)
