Reaction Steps
Under Ar, the mixture of cyclopropanecarboxylic acid (500 mg, 5.81 mmol), diphenylphosphoryl azide (1.58 g, 5.81 mmol), and triethyl amine (0.81 mL, 5.8 mmol) in 3 mL of N,N-dimethyl-formamide was heated to 80° C. for 3 hours. The mixture was cooled to room temperature, 3-amino-6-chloro-2-hydroxybenzenesulfonamide (200 mg, 0.89 mmol) was added. The resulting mixture was stirred at room temperature for 20 hours. Purification upon Gilson HPLC, eluting with acetonitrile/water (10/90, v/v to 90/10, v/v, over 10 min), gave the desired product (74 mg, 27%). LC-MS (m/z) 306.2 (M+).
