Paragraph 0237; 0238; 0239, (2016/10/08)
PROBLEM TO BE SOLVED: To provide a simple method for producing a production intermediate of a polyethylene glycol derivative, and further to provide a large number of compounds useful as effective components of an antitumor agent by virtue of the method. SOLUTION: A polyethylene glycol monoether compound represented by formula (1) (in the formula, R represents a hydrocarbon group that may contain a substituent, and n represents a positive integer) or its salt is produced by using a compound resulting from esterifying one hydroxy group alone of a polyethylene glycol compound with a p-toluenesulfonyl group.
