Procedure
4-(2-Thienyl)tetrahydropyran-4-carboxylic acid was reacted with thionyl chloride and a catalytic amount of DMF in methylene chloride under heating to obtain 4-(2-thienyl)tetrahydropyran-4-carbonyl chloride. A THF solution of 4-(2-thienyl)tetrahydropyran-4-carbonyl chloride was added dropwise to a THF solution of hydrazine monohydrate and the whole was reacted at 0° C. to obtain 4-(2-thienyl)tetrahydropyran-4-carbohydrazide.
Workup
- customthe whole was reacted at 0° C.
