Reaction Steps

A solution of Example 270 (200 mg, 0.25 mmol, 1.0 eq) and triethylamine (50.5, 0.50 mmol, 2.0 eq) in dichloromethane (5 mL) under N2 was cooled to 0° C. 4-(chlorosulfonyl)benzoic acid (55.15 mg, 0.25 mmol, 1.0 eq) was added and the reaction warmed to room temperature and monitored by LCMS. After 2 hours, the resulting solution was diluted with dichloromethane (20 mL) and washed with water (2×20 mL). The organic layer was acidified to pH 5 with 1N HCl and washed with water (20 mL), brine, and dried over Na2SO4. Removing the solvent resulted in 172 mg of 4-(N-(15-(3-(4-(diethylamino)-2-(4-(3-(trifluoromethyl)benzylcarbamoyl)pyridin-2-yl)phenylcarbamoyl)phenyl)-3,6,9,12-tetraoxapentadecyl)sulfamoyl)benzoic acid as an oil.
