Boronic acid 4 (400 mg, 1.02 mmol) is coupled to 4-bromobenzene-sulfonamide (241 mg, 1.02 mmol) using Method A. On filtration of the cooled reaction mixture through celite and removal of the solvents in vacuo, the crude residue obtained is used in the next synthetic step without further purification.
