Versuchsvorschrift
It is known that 3-(2-hydroxyethyl)butyrolactone can be reacted with methanol to give esters of tetrahydropyran-4-carboxylic acid (EP-A-284 969). This reaction results in a mixture containing esters of tetrahydropyran-4-carboxylic acid, 3-(2-hydroxyethyl)butyrolactone, 3-(2-methoxyethyl)butyrolactone, 3-spirocyclopropylbutyrolactone, methanol, possibly water, possibly acetic acid and possibly methyl acetate, which involves problems in working up.
