Hydrochloric Acid → 3,5-Diethoxy-4-isoxazol-4-yl-benzoic acid

Participants

Reaction Steps

Methyl 3,5-diethoxy-4-(isoxazol-4-yl)benzoate (91 mg) was dissolved in a mixed solvent of methanol/THF (8 mL, 3/5), aqueous 1 M NaOH solution (1.2 mL) was added to it, and stirred at room temperature for 5 hours. Aqueous 1 M HCl solution (1.2 mL) was added to it, and the solvent was concentrated under reduced pressure. The formed solid was taken out through filtration, washed with water, and dried under reduced pressure to obtain the title compound as a pale yellow solid.
