    摘要: Pyridines substituted in the 2-position by an aromatic or heteroaromatic group are prepared by reacting an aliphatic aromatic or aliphatic heteroaromatic ketone with an aliphatic oxo compound having a carbon to carbon ethylenic double bond on the carbon atom adjacent to the oxo group and ammonia in the presence of a dehydrating and dehydrogenating catalyst at a temperature of about 250.degree. to 550.degree. C.
