Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 1003-68-5, name is 5-Methylpyridin-2(1H)-one. A new synthetic method of this compound is introduced below., Recommanded Product: 5-Methylpyridin-2(1H)-one
EXAMPLE 1 5-Methyl-1-phenyl-2-(1H)-pyridone SPC3 A finely pulverized mixture containing 21.8g. of 5-methyl-2-(1H)-pyridone (J.V. Scudi, et al. U.S. Pat. No. 2,947,755), 30.4g. of anhydrous potassium carbonate, 0.25g. of zinc precipitated copper powder and 40 ml. of iodobenzene is stirred mechanically and refluxed for 18 hours. The mixture is cooled and treated with 150 ml. of benzene, filtered and the filtrate is decolorized with charcoal. The decolorized benzene filtrate is then evaporated to an oil which on trituration with petroleum ether and cooling gives 31.9g. (85%) of the product as a brown solid, m.p. 90-104. It is crystallized from hot water to yield a white solid melting at 102-psi.
