Procedure

A solution of 5.01 g of 3,4-difluoro nitrobenzene, 5.1 g (3R)-1-allyloxycarbonyl-3-amino pyrrolidine (30 mmol) and 6,27 ml of triethylamine (31.5 mmol) in 100 ml of ethyl acetate was stirred at reflux. The reaction was monitored by HPLC. The reaction was diluted with ethyl acetate, washed with water and brine, the org. layer dried over Mg sulfate, filtered and evaporated. The residue crystallized from an ether/hexane mixture.
