Abstract

PURPOSE:To easily obtain the subject ester of a specific formula, having medium to high boiling point, useful as e.g. a solvent for resins intended for resists, by using industrially readily available raw materials. CONSTITUTION:This ester is expressed by formula I (R<1> and R<2> are each H or methyl; R<3> is methyl or ethyl; R<4> is a 1-4C alkyl) (e.g.-3-methoxypropionic-1- methyl-2-methoxyethyl ester). This ester is obtained, for example, by dehydrating esterification between a 3-methoxypropionic acid compound of formula II and a 1-alkyl-2-alkoxyethyl alcohol compound of formula III in the presence of an acid catalyst.
