PROCEDURE

实验过程

15 g. Rifamycin S are dissolved in 50 ml. dimethylformamide and 5.5 g. 1,3,5-tri-(tert.-butyl)-hexahydro-1,3,5-triazine are added to the solution. The reaction mixture is then kept at 75° C. for about 3 hours and 1-amino-4-methylpiperazine, acidified with acetic acid, added directly according to the procedure described in Example 1, followed by analogous working up to give substantially pure rifampicin.
