To a suspension of 450 mg (1.7 mmol) 3-iodo-N-methyl-isonicotinamide in 10 ml toluene were added successively 60 mg (0.05 mmol) tetrakis(triphenylphosphine)palladium(0), 2.5 ml 2 M sodium carbonate solution in water and 342 mg (2.5 mmol) o-tolylboronic acid. The mixture was heated under argon at 80° C. for 20 h. The aqueous layer was separated and washed twice with toluene. The combined organic layers were washed with brine, dried (magnesium sulfate) and evaporated. Chromatography of the residue afforded 341 mg (87%) of the title compound as a light yellow solid. M.p. 90-92° C.
