Reaction Steps

To a solution of {2-[4-(3-aminophenyl)phenoxy]propyl}[(methylethyl)sulfonyl]amine (125 mg, 0.3587 mmol, prepared in example 3) dissolved in methylene chloride (2.5 mL, anhydrous) was added triethylamine (0.125 mL, 0.8968 mmol) under a nitrogen system. The mixture was cooled to 0° C. and 2-propanesulfonyl chloride (0.06 mL, 0.5381 mmol) was added by syringe. The mixture was allowed to warm to room temperature, and stirred overnight, under a nitrogen system. The reaction was quenched with excess water, and the organic layer was dried with anhydrous sodium sulfate, filtered, and concentrated under reduced pressure, yielding 431 mg viscous oil. Purification was conducted using a Chromatotron®, on a 4000 μm rotor and eluting with a 1:1 hexane:ethyl acetate solvent system, yielding 400 mg of two inseparable coeluting spots. This mixture was purified by reverse phase chromatography on a Vydac C-18 column on a gradient of 5 to 70% of 0.1% trifluoroacetic acid/acetonitrile in water over 45 minutes at 200 mL/min elution rate, yielding the title compound (16.7 mg, 1%) as a slow crystallizing foam.
