According to the method, alpha-(4-chlorphenyl)-2- pyridinemethanol is used as raw materials and reacts with 4-hydroxide radical piperidine under the catalytic action of lewis acid in one step to obtain the 2-[(4- chlorphenyl) (4-piperidyl oxygroup) methyl] pyridine. The method is ...
Ethylene and ammonia react in the presence of a palladium complex catalyst to give 2-methylpyridine and MEP. Pyridine can be prepared from cyclopentadiene by ammoxidation, or from 2-pentenenitrile by cyclization and dehydrogenation. Furfuryl alcohol or furfural reacts with ammonia in the gas phase ...
3,5-Dichloropyridine-4-carboxaldehyde reacts with thiophenol to produce a diaryl sulfide. The diaryl compound and methyl thioglycolate undergo an aldol-type cyclization reaction in the presence of a weak base to afford 4-substituted thieno[2,3-c]pyridine derivative 121 (Scheme 38) <2002JOC943>...
Sodium hydroxide treatment of the methiodide of pyrrolo[2,3-b]pyridine gives a stable free base which reacts with a second molecule of methyl iodide, this time at the pyrrole nitrogen (Scheme 4). The resonance stabilization of the free base is shown by its stability towards boiling 20% ...
