To a solution of 4-Fluoro-3-nitro-N-[3-(2-oxo-pyrrolidin-1-yl)-propyl]-benzamide (2.0 g, 6.47 mmol) in DMF (10 mL), K2CO3 (1.7 g, 12.94 mmol) was added followed by 1-o-tolyl-piperazine (1.7 g, 9.7 mmol), and the reaction mixture was stirred at room temperature for 16 h. DMF (2.0 mL) was added and filtered. The solid was washed with MeOH (300 mL) and methanol layer was evaporated to give the acid 3-nitro-N-[3-(2-oxo-pyrrolidin-1-yl)-propyl]-4-(4-o-tolyl-piperazin-1-yl)-benzamide in the first crop (1.8 g, 62%).
