Sodium Hydroxide → HCID 58047468, compound

Participants

Reaction Steps

To a solution of 5-ethoxy-2-[(trimethylsilyl)ethynyl]pyridine (2.74 g) in methanol (40 mL) was added 8M aqueous sodium hydroxide solution (3.73 mL) at room temperature, and the reaction mixture was concentrated under reduced pressure. The residue was diluted with ethyl acetate and water, and the aqueous layer was separated from the organic layer. The separated aqueous layer was extracted again with ethyl acetate. The combined organic layer was washed with saturated brine, and dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (hexane/ethyl acetate) to give the title compound as a pale-brown powder (1.72 g).
