実験手順

3-Iodo-4-methylbenzoic acid (154 mg, 0.59 mmol) was heated at 80° C. in thionyl chloride (2 ml) for 3 hrs. The reaction was allowed to cool to room temperature and the excess thionyl chloride evaporated under vacuum. The residue was dissolved in acetone (3 ml), 2-(3-aminophenyl)pyridine (100 mg, 0.59 mmol) and sodium carbonate (400 mg) were added to the solution. The reaction was stirred at room temperature for 11 ldays, filtered and the filtrate reduced to dryness under vacuum. The residue was dissolved in ether and filtered through a bond-elut (1 g, silica), washing with ether. The solvent was evaporated from the combined filtrate and washings to give 3-iodo-4-methyl-N-(3-pyridin-2-yl-phenyl)benzamide as a cream foam. NMR: δH CDCl3 8.70,(1H, dt), 8.33,(1H, d), 8.18,(1H, t), 7.93-7.89,(2H, m), 7.79-7.75, (4H, m), 7.50,(1H, t), 7.35,(1H, d), 7.26,(1H, m), 2.51,(3H, s).
