220210-56-0 - Reference Information
| application | 3-(tert-butoxycarbonyl)-phenylboronic acid can be used as an intermediate in organic synthesis and pharmaceutical intermediate, mainly used in laboratory research and development process and chemical production process. |
| prepare | 10L glass reactor with mechanical stirring, thermometer and constant pressure dropping funnel, add 3 moles of raw material m-carboxyphenylboronic acid and 4kg of tetrahydrofuran under nitrogen protection, add 4.5 moles of sulfoxide chloride dropwise under reflux stirring, react for 4 hours, cool down to 0-5 ℃, add 7.5 moles of potassium tert-butoxide in batches, and continue stirring for 1 hour after adding, add 2kg of water, acidify with acetic acid, stand still, and separate liquid. The organic phase was concentrated to obtain crude product, and 2kg of petroleum ether was added to recrystallize to obtain solid product 3-(tert-butoxycarbonyl)-phenylboronic acid with 98% purity and 95% molar yield. |
