実験手順

3.1 mL of triethylamine and 1.3 mL of benzoyl chloride were added to 19 mL of methylene chloride solution containing 1.9 g of methyl 2-amino-4-methoxybenzoate while ice-cooled sequentially and stirred at room temperature for 3 hours. The solvent was evaporated under reduced pressure and chloroform and 1.0 mol/L hydrochloric acid were added to the obtained residue. The organic layer was separated and dried over anhydrous magnesium sulfate after washed with a saturated sodium hydrogen carbonate aqueous solution and a saturated sodium chloride aqueous solution sequentially, and the solvent was evaporated under reduced pressure. Hexane and diisopropyl ether were added to the obtained residue and a solid substance was separated by filtration to obtain 2.6 g of methyl 2-(benzamido)-4-methoxybenzoate as white solid.
