摘要: A method of producing a polyoxyethylene derivative (1): where L1 is a divalent linker, X is a functional group capable of reacting with a physiologically active substance, a is 1 or 2, and n is from 11 to 3,650. The method includes Step (A): protecting 4 or 6 hydroxyl groups in a polyhydric alcohol having 5 or 7 hydroxyl groups by cyclic benzylidene acetalization to obtain a compound having a hydroxyl group at a 1-position and a protective group of a cyclic benzylidene acetal structure; Step (B): polymerizing from 11 to 3,650 moles of ethylene oxide to the compound obtained in the step (A) to obtain a polyoxyethylene derivative; Step (C): converting the hydroxyl group at a terminal of the polyoxyethylene derivative to a functional group capable of reacting with a physiologically active substance; and Step (D): deprotecting the protective group of the polyoxyethylene derivative.
