Tetrabutylammonium Fluoride → HCID 86229373, compound

Participants

Reaction Steps

A mixture of 5-(4-methoxyphenyl)-1-((6-(2-(trimethylsilyl)ethynyl)pyridin-3-yl)methyl)pyridin-2(1H)-one (0.60 mmol, 240 mg), tetrabutylammonium fluoride (1.20 mmol, 1.2 mL) in THF (5 mL) and H2O (1 mL) was stirred at room temperature for 2 hours. The solvent was evaporated under reduced pressure. The residue was taken up in CH2Cl2, washed with water, dried (Na2SO4) and evaporated under reduced pressure. The residue was purified in a manifold (vac.) using a Sep-Pak silica cartridge CH2Cl2/MeOH(NH3)sat. 3%. The fractions were collected and evaporated. The residue thus obtained was triturated with diisopropyl ether. The precipitated solid was filtered off and dried. Further purification by circular chromatography-TLC CH2Cl2/MeOH(NH3)sat. 3% yielding 1-((6-ethynylpyridin-3-yl)methyl)-5-(4-methoxyphenyl)pyridin-2(1H)-one (68 mg, 35%).
