| titleOfInvention | PROCEDURE TO PREPARE A DERIVATIVE OF RIFAMYCIN SV. |
| abstract | Process for preparing a rifamycin SV derivative comprising refluxing rifamycin S in an inert organic solvent with at least two equimolar amounts of formaldehyde and an excess on an equimolar amount of a secondary nitrogenous base selected from an amine formula ** (See formula) ** wherein R is a member selected from the group consisting of hydrogen and a lower alkyl, R 'is a member of the class consisting of lower alkyl, lower hydroxy alkyl, lower alkyl carboxy and alkyl alkyl radical and a heterocyclic compound of formula wherein X is a member of the class consisting of methylene, ethylene, a radical -CH2O and a radical -CH2 NH-, R '"are members of the class consisting of hydrogen, lower alkyl, hydroxy and carboxy radicals , by contacting the obtained aminomethyl derivative of rifamycin S with an aqueous solution of ascorbic acid.
