3-Carboxyphenylboronic acid

25487-66-5

1. Synthesis of 3-carboxyphenylboronic acid: 10 g (68 mmol) of 3-cyanophenylboronic acid was suspended in 40 mL of ethylene glycol with 15.26 g (272 mmol, 4 eq.) of potassium hydroxide powder, heated to 175 °C and maintained for 3 hours. After completion of the reaction, the reaction mixture was cooled and diluted with 60 mL of water. The pH was adjusted to 2-3 with 32% hydrochloric acid solution, colorless crystalline 3-carboxyphenylboronic acid was precipitated and the product was separated by filtration. The resulting crystals were washed with water and dried under mild vacuum at 35 °C. The final product was 10.04 g in mass. The final product was 10.04 g (60.5 mmol, 89% yield).
