Reaction Steps

To a stirred solution of 4-fluoro-2-nitrotoluene (50.0 g, 0.327 mol) in DMF (100 mL) was added DMF-DMA (52 mL, 0.392 mol) and pyrrolidine (33 ml, 0.392 mol) in DMF (100 mL). The reaction mixture was stirred at reflux overnight and then concentrated under reduced pressure, giving 84 g of the title compound.
