Reaction Steps

4-Chlorbenzenesulfonyl isocyanate (150 mg) was dissolved in CH2Cl2 (2 mL). 2-Amino-4-brompyridine (132 mg) was added to the mixture. After that the mixture was stirred for 18 h at 25° C. The obtained white precipitate was filtered off and washed with CH2Cl2 and dried in vacuo to yield N-[(4-bromopyridin-2-yl)carbamoyl]-4-chlorobenzenesulfonamide (111 mg; 41%) as a white solid.
