2-Vinylpyridine → HCID 18993324, compound

Participants

Reaction Steps

A mixture of 3-(diphenylhydroxymethyl)piperidine (267 mg, 1.0 mmol), 2-vinylpyridine (0.32 g, 3.0 mol) and Triton B (3 drops) in 1-butanol (10 ml) was heated under reflux for 18 hours, diluted with water and ethyl acetate and the layers separated. The organic layer was washed with water, dried over magnesium sulphate and evaporated. The residue was twice taken up in toluene and evaporated and it was then purified by chromatography on SiO2 using dichloromethane plus 0-5% methanol as eluant. Appropriate fractions were combined and evaporated to give the title compound (80 mg) as a pale brown oil which was characterised containing 0.25 equivalents of water.
