Methyl 3-amino-4-hydroxybenzoate → HCID 58001321, compound

Participants

Reaction Steps

(4-tert-butyl-phenoxy)-acetic acid (200 mg, 0.96 mmol) and 3-amino-4-hydroxy-benzoic acid methyl ester (240.7 mg, 1.44 mmol) were dissolved in PPSE (3 mL), and reacted for 2.5 h at 140° C. After saturated sodium bicarbonate aqueous solution was added, organic phase was washed with 10% HCl and brine. The organic phase was dried (MgSO4 anh), and concentrated. The residue was purified by silica gel column chromatography (n-Hexane:Ethyl acetate:MeOH=15:3:1) to give 3-[2-(4-tert-butyl-phenoxy)-acetyl-amino]-4-hydroxy-benzoic acid methyl ester as an orange solid (350 mg, 89% yield).
