2.1 mL of benzoyl chloride was added to 70 mL of a methylene chloride solution containing 3.5 g of 5-iodo-2-methylaniline and 2.5 mL of triethylamine at room temperature and stirred at the same temperature for 30 minutes. 1.0 mol/L hydrochloric acid was added to the reaction mixture. The organic layer was separated and dried over anhydrous magnesium sulfate after washed with a saturated sodium hydrogen carbonate aqueous solution, and the solvent was evaporated under reduced pressure. Diisopropyl ether and hexane were added to the obtained residue and a solid substance was separated by filtration to obtain 4.2 g of N-(5-iodo-2-methylphenyl)benzamide as pale yellow solid.
