Reaction Steps

2-Bromo-4-fluoronitrobenzene (949 mg, 4.31 mmol) was added in two portions to neat N-methypiperazine (8 mL) at 0° C. and allowed to warm to room temperature. The reaction was heated to 60° C. for 1 h, and then it was diluted with 50 mL of EtOAc and poured into H2O (50 mL). The layers were separated and the organic layer was washed with satd aq NaHCO3, dried (Na2SO4), and concentrated in vacuo to afford 580 mg (45%) of the title compound as a yellow solid: Mass spectrum (ESI, m/z): Calcd. for C11H14BrN3O2, 300.0 (M+H), found 300.1.
