実験手順

3-Cyano-5-ethyl-6-methyl-2-(1H)-pyridinone (22.9 g, 0.141 mol) and phosphorus pentachloride (33.1 g, 0.159 mol) were intimately mixed and heated at 110°-120° C. for one hour. The liquified solids were poured onto crushed ice and water and the semi-solid was extracted into chloroform. This extract was washed with water, saturated aqueous NaHCO3, dried (Na2SO4), filtered and evaporated. This amber oil was dissolved in hexane and the insoluble material was removed when filtered through a pad of charcoal. Removal of the solvent gave a light yellow oil which solidified (17.7 g). Trituration of this solid with cold hexane yielded 15.6 g (61%) of pure product, m.p. 63°-64° C.
