Abstract

Procedure for the preparation of substituted cobamides, such as α - (5,6-dimethylbenziminazolyl) -methyl-cobamide, characterized by being exposed to white light and reducing alpha- (5,6-dimethylbenzimrtazolyl) -hydroxo-cobamide, poured into a column loaded with ion exchange resins and react the solution with a methyl halide and finally pour into a column containing a non-ionic resin of the adsorbent type.
