Reaction Steps

A solution of N,N-dimethyl-3-amino-6-chloro-2-hydroxybenzenesulfonamide (80 mg, 0.32 mmol) and 2-bromophenylisocyanate (47 μL, 0.38 mmol) in 2 mL of N,N-dimethylformamide was stirred at room temperature for 20 hours. The mixture was diluted with ethyl acetate and washed with water to give the crude material. Purification by column chromatography on silica gel, eluting with ethyl acetate/hexane (20/80, v/v), followed by recrystallization from ethyl acetate and hexane, gave the desired product (88 mg, 62%). EI-MS (m/z) 446.2, 448.3, 450.3 (M−).
