Procedure

To a stirred solution of 1-[(E)-2-(4-fluoro-2-nitrophenyl)ethenyl]pyrrolidine (77.25 g, 0.327 mol) in warm MeOH (500 mL) was added a solution of semicarbazide HCl (38.3 g, 0.343 mol) in warm water (200 mL). The reaction mixture was stirred at room temperature for 1 h and was then cooled in ice and filtered. The solid was washed with cold 1:1 MeOH/water (2×30 mL) and dried to give 71 g (90% over two steps) of the title compound.
