Paragraph 0057; 0058; 0060, (2018/04/18)
PROBLEM TO BE SOLVED: To provide a method for producing a piperidine compound in an industrially convenient manner. SOLUTION: This invention relates to a method for producing a compound represented by general formula (I) or a salt thereof that includes the step of converting a pyridine compound having an alkynylene group in a side chain, by a contact hydrogenation reaction, into the compound represented by general formula (I) or a salt thereof (in the general formula (I), R1 is a hydrogen atom, a hydroxy group, or an optionally substituted alkyl group having carbon atoms of 1 or more and 20 or less).

Monoalkynylpyridines were prepared via a Sonogashira cross-coupling reaction between monoiodopyridines and alkynes. Mild hydrogenation of the obtained monoalkynylpyridines was then conducted to produce the corresponding monoalkylpiperidines in moderate to excellent yields. The hydrogenation reaction was carried out under H2 (1?atm) in the presence of 10?wt% Pd/C (5?eq) in either AcOH or MeOH at room temperature. The present mild method is therefore useful for the quick and easy preparation of monoalkylpiperidines.
