Procedure
In a 250 mL 3 neck flask fitted with a stirrer and thermometer, 356 mg of 2-propanesulfonyl chloride is added dropwise to 350 mg of {2-[4-(3-aminophenyl)phenyl]-2-fluoropropyl}[(dimethylamino)sulfonyl]amine (prepared in example 38) and 380 mg of DBU in THF (125 mL) while stirring at 0° C. under a nitrogen atmosphere. The reaction is allowed to warm to room temperature and then stirred overnight at this temperature. In the morning, the reaction is concentrated under reduced vacuum. The resulting material is taken into ethyl acetate and the organic layer is washed two times with H2O, dried over Na2SO4, filtered, and concentrated under reduced vacuum. This crude material is purified via silica gel chromatography employing the Chromatotron and using a 4000 micron rotor with hexane/ethyl acetate eluent to provide the title compound.
