Versuchsvorschrift

A 50 mL flask fitted with a stirrer and thermometer was charged with DBU (67 mg, 1.1 eq), {2-[4-(3-aminophenyl)phenyl]-2-fluoropropyl}[(methylethyl)sulfonyl]amine (140 mg, 0.44 mmol, prepared in example 5) and methylene chloride (10 mL) under an atmosphere of nitrogen, and cooled to 0° C. To this stirring solution was added dropwise chloro-methane sulfonyl chloride (69 mg, 1.5 eq). The reaction was allowed to warm to room temperature and stirred overnight at this temperature. In the morning, the mixture was poured into H2O and the layers were separated. The organic layer was washed once with H2O, dried over anhydrous Na2SO4, filtered, and concentrated under reduced vacuum to yield the crude material (192 mg) as a yellow oil. This crude material was purified via silica gel chromatography employing the Chromatotron using a 4000 micron rotor and eluting with a solvent of Methylene Chloride/ethyl acetate 9:1 to yield the title compound (50 mg, 29%) as a white foam. Ion spray mass spectra 427.1 (M*−1).
