반응 단계
A mixture of ethyl 3-hydroxypicolinate (15 g, 900 mmol), tributylsilyl chloride (16.23 g, 110 mmol), imidazole (8.0 g, 120 mmol) in methylene chloride was stirred overnight under a nitrogen atmosphere. Water was added and the methylene chloride layer was separated and concentrated in vacuo. Purification on a silica gel column using ethyl acetate-hexane (1:4) as the eluant gave ethyl 3-(tributylsilyloxy)picolinate as a solid (20 g).
