Source of material

All chemicals, reagents and solvents are of analytical grade and are commercially available. Preparation of 4-bromo-2,5-difluorobenzenesulfonyl chloride: 2-bromo-1,4-difluorobenzene (10.00 g, 52 mmol) was dissolved in 100 mL CH2Cl2. To this solution, chlorosulfonic acid (30.18 g, 260 mmol) was added over a period of 20 min at 0 °C. After the addition was complete, the mixture was stirred at room temperature for 5 h. The reaction mixture was poured into 60 g ice water, and then extracted with dichloromethane. The organic phase was dehydrated with anhydrous sodium sulfate and concentrated at reduced pressure to afford a light yellow powder (14.05 g, 93%). Preparation of 4-bromo-N-cyclopropyl-2,5-difluorobenzenesulfonamide: A mixture of 4-bromo-2,5-difluorobenzenesulfonyl chloride (12.00 g, 41 mmol), cyclopropylamine (2.80 g, 49 mmol), and triethylamine (8.30 g, 82 mmol) in 100 mL dichloromethane was stirred at room temperature for 3 h. The mixture was concentrated at reduced pressure, and the residue was washed with 60 mL water and crystallized from n-hexane to afford pure product (11.60 g, 91%).

Experimental details

All hydrogen atoms were placed in geometrically calculated positions. The Uiso values of the hydrogen atoms of methyl groups were set to 1.5Ueq(Cmethyl) and the Uiso values of all other hydrogen atoms were set to 1.2Ueq(C).

Discussion

The hepatitis C virus is a leading cause of liver disease and represents a serious health concern [3]. The treatment with non-nucleoside thumb pocket 2 HCV NS5B polymerase inhibitors has made a great progress [4]. Phenyl sulfonamide and its derivatives can be used as an important intermediate in the synthesis of non-nucleoside thumb pocket 2 HCV NS5B polymerase inhibitors. In addition, it has been reported that phenyl sulfonamides can also be used to synthesize the tyrosine kinase inhibitor, which shows anti-cancer effect [5].

All bond lengths and angles are in the expected ranges. Particularly, the bond length of C—Br bond is 1.884 Å. In addition, the bond length of C2–F5 and C5–F1 are 1.349 Å and 1.353 Å, respectively. The angle of C4S1N1 is 108.55° due to the steric stabilization. Title molecules are pairwise connected by classical N—H⋯O hydrogen bonds. The molecules packing in the crystal structure is additionally stabilized by weak intermolecular C—H⋯O hydrogen bonds.
