Reaction Steps
To a solution of Tetrahydro-furan-3-carboxylic acid (0.093 mL, 1.0 mmol) in DMF (0.5 mL) was added DPPA (0.25 mL, 1.2 mmol) and TEA (0.25 mL, 1.8 mmol) and the reaction heated at 70° C. After 18 hrs, 3-Amino-6-chloro-2-hydroxy-benzenesulfonamide (1.0 mmol) was added and the reaction heated at 70° C. After 18 hrs, the reaction mixture was quenched with water and extracted with ethyl acetate. The organic layers were dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The crude residue was purified via HPLC to give 18 mg (5%) of N-[4-chloro-2-hydroxy-3-sulfamylphenyl]-N′-(3-tetrahydrofuryl)urea. LC-MS (m/z) 336 (M+).
