Abstract: 543,615. Vitamin B6. MERCK & CO., Inc. March 27, 1940, No. 5488. Convention date, April 13, 1939. [Class 2 (iii)] Vitamin B6 is prepared by nitrating 3-cyanc- 4-ethoxymethyl-6-methyl-2-pyridone, halogenating the 5-nitro product to give 2-methyl-3- nitro - 4 - ethoxymethyl - 5 - cyano - 6 - halogen - pyridine, reducing with hydrogen first to convert the nitro group to amino and then both to dehalogenate and reduce the cyano group, diazotizing and hydrolysing the resulting 2- methyl - 3 - amino - 4 - ethoxymethyl - 5 - aminomethyl-pyridine to convert the amino groups into hydroxy groups and finally hydrolyzing the 2-methyl-3-hydroxy-4-ethoxymethyl- 5-hydroxymetbyl-pyridine either directly or after first forming the 4:5-di (halogenmethyl)- compound by tieatment with a hydrohalic acid. An example is given together with a diagrammatic representation of the series of re-actions involved. In the example, the nitration step is carried out by the use of fuming nitric acid or ferric nitrate in acetic anhydride, the halogenation is effected with phosphorus pentachloride giving 2-methyl-3-nitro-4-ethoxymethyl-5-cyano-6-chloropyridine, the treatment with hydrogen takes place in the presence of platinic oxide or a mixture of platinic oxide and palladium charcoal respectively as catalyst, and the bydrohalic acid used is hydrobromic acid whereby 2-methyl-3-hydroxy-4:5-di- (bromomethyl)-pyridine is obtained. The Specification as open to inspection under Sect. 91 refers also to the use of starting materials in which the ethoxy radicle'. of the ethoxymethyl group is replaced by other alkoxy radicles or by aroxy, halogen, acyloxy and hydroxy, or in which the pyridine is substituted in the 1-position by alkyl or aryl. A material containing a 1-methyl group is prepared by treating 3-cyano-4-ethoxymethyl-6-methyl-2- pyridone with sodium methylate and refluxing with methyl iodide. This subject-matter does not appear in the Specification as accepted. 3-Cyano-4-ethoxymethyl-6-methyl-2-pyridone is prepared by condensing ethoxy-acetylacetonewith cyanacetamide in alcoholic solution in presence of piperidine.
