摘要：
This invention relates to a method of producing a compound represented by the following general formula (3):
[wherein R is a bivalent aliphatic group having a carbon number of 1-16 or a bivalent aromatic group], which comprises a step (i) of reacting a compound represented by the following general formula (1):
with a carboxylic acid halide represented by the following general formula (2):
[wherein R is a bivalent aliphatic group having a carbon number of 1-16 or a bivalent aromatic group and X is a halogen atom] in the presence of a basic compound to form an ester, and a step (ii) of conducting a heat treatment after the step (i) to decompose an oligomer in the ester.
