Procedure

14 ml trifluoroacetic acid were added to a mixture of 2.8 g [trans-3-(5-fluoro-2-nitrophenoxy)-cyclobutyl]-carbamic acid tert-butyl ester in 100 ml methylene chloride at 0° C. The mixture was stirred then for 2 hours at rt and afterwards concentrated. The residue was stirred with diisopropylether and filtered.
