BETA,BETA-TETRAMETHYLENEGLUTARIMIDE - Reference Information
| NIST chemical information | information provided by: webbook.nist.gov (external link) |
| Application | 3, 3-tetramethylene glutarimide is a commonly used intermediate in the preparation of certain drugs, at present, most of them are used for the preparation of anti Anxiety drug buspirone hydrochloride, and are the key intermediates for the preparation of this kind of drugs. |
| preparation | CN92108607.5 a new preparation method of 3, 3-tetramethylene glutarimide is reported: 1,1-cyclopentane diacetic acid and urea in the ratio of 1: 1.1-1: 1.6 (molar ratio), at 0.5-200 deg C stirring reaction for -2 hours, after the reaction, the crude 8-azaspiro [4,5] decane -7, 9-dione compound was obtained, and then recrystallized from 30-60% ethanol and activated carbon to obtain white crystal 3,3-tetramethylene glutarimide compound, yield 80.1-89.5%, melting point 154-156 °c. The urea used is a commercially available and inexpensive raw material, and there is no special requirement for the reaction equipment because no acetic anhydride is used. At the same time, the method of the present invention simplifies the reaction steps compared with the prior art, the invention has low cost of raw and auxiliary materials and simple equipment. The advantage of a short reaction time. Particularly suitable for industrial production. |
