Procedure
82 mg of potassium carbonate and 0.047 mL of benzyl bromide were added to 1 mL of N,N-dimethylformamide solution containing 80 mg of methyl 2-(benzamido)-4-hydroxybenzoate at room temperature and stirred at the same temperature for 3 hours. Ethyl acetate and 1.0 mol/L hydrochloric acrd were 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 a saturated sodium chloride aqueous solution sequentially, and the solvent was evaporated under reduced pressure. Hexane was added to the obtained residue and a solid substance was separated by filtration to obtain 75 mg of methyl 2-(benzamido)-4-(benzyloxy)benzoate as white solid.
