Triethylamine → Tert-butyl 4-(benzo[1,3]dioxol-5-yl)-2-(4-fluorobenzamido)benzoate

Participants

Reaction Steps

0.054 mL of triethylamine and 0.034 mL of 4-fluorobenzoyl chloride were added to 3.5 mL of methylene chloride solution containing 60 mg of tert-butyl 2-amino-4-(benzo[1,3]dioxol-5-yl)benzoate at room temperature sequentially and stirred at the same temperature for 5 hours. A saturated sodium hydrogen carbonate aqueous solution was added to the reaction mixture, and the organic layer was separated, and the solvent was evaporated under reduced pressure. The obtained residue was purified with silica gel column chromatography [Flash Tube 2008 manufactured by Trikonex Company, eluent; hexane:ethyl acetate=4:1]to obtain tert-butyl 4-(benzo[1,3]dioxol-5-yl)-2-(4-fluorobenzamido)benzoate.
