Title: New isonicotinic thioamides and their process of preparation
IPC: C07D213/85
Filed: 1957-03-26
Abstract: a -Substituted isonicotinic thioamides, where the substituent is alkyl, aryl, or aralkyl, are prepared by the following series of reactions: (a) the ketone RCOCH2 is condensed with an oxalic acid diester in the presence of an alkali metal alcoholate to form an acyl-pyruvic acid ester; (b) the latter is condensed with cyanacetamide in the presence of a nitrogeneous base such as piperidine to form an ester of 6-R-3-cyano-4-carboxy-2-pyridone, which is (c) treated with hot concentrated HCl to form 6-R-4-carboxy-2-pyridone; (d) chlorination with POCl3+PCl5 gives the 6-R-2-chloro-4-acylchloride, which is then extracted with alcohol and esterified; (e) catalytic hydrogenation removes chlorine to form the a -substituted isonicotinic acid ester; (f) the ester is treated with NH3 to form the acid amide, which is treated with P2O5 to give the nitrile; (g) the nitrile, in an anhydrous solvent such as ethanol, is treated with H2S, in the presence of a tertiary nitrogenous base, such as triethanolamine.  In an alternative procedure for the case of a -methyl-isonicotinic thioamide, pyruvic acid is condensed with NH3 in an alcoholic medium to form uvitonic acid, which is decarboxylated at about 300 DEG  C. to a -methyl-isonicotinic acid; the acid is esterified, and the ester then treated by steps (f) and (g) above. In examples, the a -substituent is methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, amyl, n-hexyl, phenyl and benzyl.

Abstract: PROBLEM TO BE SOLVED: To prevent irregular developing by forcibly projecting a liquid phase developer toward a developer carrier by an electrode part. SOLUTION: The sheet-like electrode part 10 is arranged so that its side edge part 10a may be proximate to a developing part over the longitudinal direction of the developing part. A power source 13 is provided in order to impress DC voltage on the electrode part 10. When the voltage is impressed on the electrode part 10 from the power source 13, a locally strong electric field is formed between the side edge part 10a of the electrode part 10 and a latent image carrier 1. In such a case, when the electric field acts on developer 3 in a thin film state held on the outer peripheral surface of a developing roller 2, the polarization of the developer 3 occurs and the projection of the developer 3 is caused in the developing part, then toner in the developer 3 gathers at the tip part of the projection. By forcibly projecting the developer 3 toward the carrier 1 by the electric field formed in the electrode part 10, the developer 3 is uniformly stuck to an electrostatic latent image.
