(5-氟-2-甲氧苯基)硼酸 - Reference Information

Application

can be used as an intermediate for a new drug of selective non-steroidal small molecule hormone receptor antagonist, which has a non-steroidal structure Therefore, the side effects of using non-selective progesterone receptor antagonist drugs such as mifepristone on the human body can be avoided.

Preparation

About the synthesis of 5-fluoro-2-methoxyphenylboronic acid There are two main methods: 1) The reaction of p-fluoroanisole and the n-butyl lithium solution dissolved in THF at -60
℃ is protected by nitrogen, and then reacted with triisopropyl borate at -70 ℃ and then acidified with hydrochloric acid; 2) React with 2-bromo-4-fluoroanisole and the n-butyl lithium solution dissolved in THF
at -78 ℃, then react with trimethyl borate at room temperature, then acidify with hydrochloric acid, and wash with ammonium chloride solution.
