Abstract
A method for producing a maleimide polyethylene glycol derivative, may including a reaction step of heating a maleimide polyethylene glycol derivative having a protective group, in a solvent in the presence of silica gel to cause deprotection. A maleimide polyethylene glycol derivative can be produced at a high maleimidization rate while restraining deterioration of a maleimide group on deprotecting the maleimide polyethylene glycol derivative having a protective group.
