[2-(methanesulfonamido)phenyl]boronic acid

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Using the procedure of Example 1, Step B, the title compounds were prepared from a mixture of (E)-5-bromo-1-methyl-2-[2-(4-trifluoromethyl-phenyl)-vinyl]-1H-benzimidazole and (E)-6-bromo-1-methyl-2-[2-(4-trifluoromethyl-phenyl)-vinyl]-1H-benzimidazole and 2-methylsulfonylaminophenyl boronic acid.

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: The title compound was prepared by a method analogous to Example 461 using (2-(methylsulfonamido)phenyl)boronic acid and 5-(4-bromo-2-fluoro-3-methoxyphenyl)pyrazin-2-amine.

Procedure: To a mixture of 5-(4-chloro-2-fluoro-3-methylphenyl)pyrazin-2-amine (75 mg, 0.32 mmol), (2-(methylsulfonamido)phenyl)boronic acid (85 mg, 0.39 mmol) and chloro(2-dicyclohexylphosphino-2′,4′,6′-triisopropyl-1,1′-biphenyl)[2-(2′-amino-1,1′-biphenyl)]palladium(II) (5.0 mg, 0.006 mmol) in a sealed tube flushed with N2 were added N2 sparged K3PO4 (1.26 ml, 0.5 N) followed by N2 sparged THF (0.63 ml). The reaction mixture was stirred at rt for 18 hours. The reaction mixture was then partitioned between EtOAc and brine. The organic layer was isolated, dried over MgSO4, filtered and concentrated to dryness. Purification by FCC afforded the title compound (100 mg, 85%).
