Reaction Steps

A mixture of N,N-diallyl-4-(3-bromophenylsulfonamido)pyridine-3-sulfonamide (0.29 g, 0.62 mmol), 5-chloro-6-methoxypyridin-3-ylboronic acid (0.15 g, 0.81 mmol), (1,1′-bis(diphenylphosphino)ferrocene)-dichloropalladium(II) (0.026 g, 0.030 mmol), cesium carbonate (0.30 g, 0.93 mmol), 1,2-dimethoxyethane (4.5 mL) and water (0.5 mL) under an atmosphere of argon was heated at 100° C. for 15 min in a microwave reactor. The reaction mixture was partitioned between ethyl acetate and diluted hydrochloric acid, the organic phase was dried over magnesium sulfate and the solvent was evaporated. Purification by column chromatography, using chloroform/methanol (98:2) as the eluent, gave the title compound in 58% yield.
