Reaktionsschritte
3-Chloro-4-fluoronitrobenzene (2.0 g, 11.4 mmol) was added to a stirred suspension of K2CO3 (1.6 g, 11.4 mmol) and N-methylpiperazine (1.3 mL, 1.17 g, 11.4 mmol) in dry DMSO (8 mL) and was heated at 100° C. for 1 h. The reaction was cooled to about 50° C. and poured into ice water (300 mL). The solid was collected by filtration, washed with water, and dried under vacuum to afford the title compound (2.43 g, 84%).
