PROCESS FOR PREPARATION OF N7-AMIDINO SUBSTITUTED MITOMYCIN C DERIVATIVES

摘要

There is disclosed a process for the preparation of N7-amidino substituted mitomycin C derivatives. The process comprises reacting mitomycin C or an N1a substituted derivative thereof such as porfiromycin with a chloroformimidinium salt in a polar solvent at low temperature. This reaction is conducted in the presence of a tertiary amine. This process eliminates the need for a strong base such as NaH prior to addition of a chlorofomimidinium salt.
