Reaction Steps
It is known that 4-hydroxymethyltetrahydropyran can be prepared in three steps: reaction of ethyl acetoacetate with ethylene oxide to form 3-(2-hydroxyethyl)gamma-butyrolactone (EP-A-246 581), rearrangement to ethyl tetrahydropyran-4-carboxylate (EP-A-284 969), and subsequent catalytic hydrogenation to form 4-hydroxymethyltetrahydropyran (DE-A-4 141 222).
