实验步骤: Using N-ethyl-4-fluorobenzamide in the general procedure for nucleophilic aromatic substitution reactions with piperazine (Scheme D), the title compound was obtained (77% yield) as a white solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 1.10 (t, J=7.07 Hz, 3 H) 2.25 (br. s., 1 H) 2.76-2.86 (m, 4 H) 3.09-3.18 (m, 4 H) 3.21-3.28 (m, 2 H) 6.90 (m, J=8.84 Hz, 2 H) 7.67-7.75 (m, 2 H) 8.11 (t, J=5.31 Hz, 1 H). ESI-MS: m/z 234.2 (M+H)+. mp=131.3-134.4° C.

反应条件: temp:0.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To a solution of ethylamine (69.4 mL, 139 mmol) and triethylamine (21.10 mL, 151 mmol) in DCM (Volume: 150 mL) was added p-fluorobenzoyl chloride (15.13 mL, 126 mmol) at 0° C. The reaction was stirred at 0° C. for 1 hr and then warmed slowly to room temperature. The reaction mixture was diluted with water. The layers were separated and the organic layer was washed with brine, dried over MgSO4, filtered, and the organic phase stripped to dryness via rotary evaporation. The organic extract was dried in vacuo to provide N-ethyl-4-fluorobenzamide (21 g, 100% yield) as a tan solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 1.12 (t, J=7.20 Hz, 3 H) 3.23-3.32 (m, 2 H) 7.24-7.33 (m, 2 H) 7.87-7.95 (m, 2 H) 8.49 (t, J=3.92 Hz, 1 H). ESI-MS:m/z 168.0 (M+H)+. mp=73.2-76.3° C. warmed slowly to room temperature The layers were separated the organic layer was washed with brine dried over MgSO4 filtered the organic phase stripped to dryness via rotary evaporation The organic extract was dried in vacuo
