METHOD FOR PRODUCING 4-HYDRAZINOTETRAHYDROPYRANE COMPOUND OR ITS ACID SALT

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a 4-hydrazinotetrahydropyrane compound or its acid salt, by which the industrially suitable 4-hydrazinotetrahydropyrane or its acid salt can simply be produced without needing a complicated operation. SOLUTION: This method for producing the 4-hydrazinotetrahydropyrane compound represented by formula (2) (R is H or a hydrocarbon group) or its acid salt is characterized by reacting a 4-substituted tetrahydropyrane compound represented by formula (1) (X is a releasing group) with hydrazine.
