Hydrochloric Acid → Methyl 2-(benzyloxy)-4-iodobenzoate

Participants

Reaction Conditions

Reaction Steps

Potassium carbonate (1.9 g) and benzyl bromide (1.2 mL) were sequentially added to an N,N-dimethylacetamide (20 mL) solution of methyl 2-hydroxy-4-iodobenzoate (2.5 g), followed by stirring at 80° C. for 1 hour. The reaction mixture was cooled to room temperature, and then 1 mol/L hydrochloric acid and ethyl acetate were added thereto. The organic layer was separated, washed with 1 mol/L hydrochloric acid and a saturated aqueous solution of sodium chloride sequentially, and dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography [Fuji Silysia Chemical Ltd., PSQ100B (spherical), eluent: 90-80% hexane/ethyl acetate] to obtain 3.3 g of methyl 2-(benzyloxy)-4-iodobenzoate as a yellow oily substance.
