PROCESS FOR PREPARING CRYSTALLINE FORMS OF A 1-CARBACEPHALOSPORIN |
| abstract |
A process for preparing the crystalline monohydrate of a 1-carbacephalosporin by adjusting the p H value of an aqueous solution of such a compound to about 2 to 7, and to processes for preparing the crystalline mono- and bis (N, N-dimethylformamide) solvate of a 1- Carbacephalosporins by reacting the corresponding and carboxy-protected 7b-amino compounds with an acylating agent in DMF and subsequent deprotection. |
