The present invention is to provide a process for preparing tetrahydropyran-4-carboxylic acid represented by the formula (1):
which comprises hydrolyzing a 4-cyanotetrahydropyran-4-carboxylic acid compound represented by the formula (2):
wherein R represents a hydrogen atom or a hydrocarbon group,
in the presence of an acid; a process for preparing a tetrahydropyran-4-carboxylic acid ester which comprises reacting the tetrahydropyran-4-carboxylic acid represented by the above-mentioned formula (1) with an alcohol in the presence of an acid; and a process for preparing tetrahydropyran-4-carboxylic acid amide which comprises reacting the tetrahydropyran-4-carboxylic acid represented by the above-mentioned formula (1) with a halogenating agent to prepare tetrahydropyran-4-carboxylic acid halide, and then, reacting an amine compound to the resulting compound.
