    摘要: A method for producing a polyoxyalkylene derivative including: step (A) in which a polyoxyalkylene derivative having hydroxyl group(s) is reacted with a phthalimide derivative in the presence of an azo reagent and a phosphine reagent; step (B) in which the phthalimide groups of the compound obtained in step (A) are deprotected using a compound having a primary amino group; and step (C) in which impurities derived from the phthalimide derivative and the deprotection reagent are removed by adsorption or extraction.

    摘要: The invention provides compound of the general formula: in which each X independently represents a polymer chain; n represents an integer greater than 1; Q represents a linker; Y represents an amide group; and Z represents either —CH.(CH2L)2 or —C(CH2L)(═CH2), in which each L independently represents a leaving group. The compounds are useful reagents for the conjugation of polymers to proteins, the resulting conjugates being novel and also forming part of the invention.
