Potassium Hydroxide → 3-(3-Benzoylphenyl)prop-2-enoic acid

関与物質

反応手順

Aqueous 5M potassium hydroxide (10 mL, 50 mmol) was added to a solution of methyl 3-benzoylcinnamate (2.5 g, 9.4 mmol) in methanol (20 mL) and the mixture was stirred at room temperature for 18 hours. The mixture was concentrated and acidified to pH 1 using 1M aqueous hydrochloric acid. The resulting precipitate was collected by filtration and dried under vacuum to give 3-benzoylcinnamic acid (2.2 g, 93%) as a yellow solid.
