Abstract
The present invention provides a novel industrially excellent and ecological process for producing methylcobalamin which is useful as a medicament etc. More specifically, it provides a process for producing methylcobalamin by reducing cyanocobalamin or hydroxocobalamin in the presence of a reducing agent, and then methylating the reductant by adding a water-soluble methylating agent.
