Procedure

A stirred solution of 4.5 g (0.015 mol) of 3-[2-fluoro-5-(trifluoromethyl)phenoxyl]-1-azetidinecarbonyl chloride in 20 mL of tetrahydrofuran was treated with 4.0 g (0.05 mol) of 40% aqueous monomethylamine. After stirring for 16 h the reaction mixture was diluted with 200 mL of water and the oil which separated slowly solidified. The solids were collected by filtration (3.9 g) and recrystallized from benzene/ligroin, yielding 3.5 g (79.8%) of white crystals, mp 93.5°-95° C.
