Chlorophenyl isocyanate → HCID 9951572, compound

Participants

Reaction Steps

A solution of 3-amino-6-chloro-2-hydroxybenzenesulfonamide (40mg, 0.18mmol) and 2-chlorophenylisocyanate (33 mg, 0.22 mmol) in 1 mL of N,N-dimethyl-formamide was stirred at room temperature for 18 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 (30/70, v/v), followed by recrystallization from acetone and hexane, gave the desired product (30 mg, 44%). EI-MS (m/z) 374.3, 376.1 (M−).
