Preparation of 3,5-dichloro-2,6-dimethyl-4-pyridinol as anticoccidiosis agent: Preparation of 3,5-dichloro-2,6-dimethyl-4-pyridinol as anticoccidiosis agent. Cheng, Libo; Sha, Jian; Fu, Heliang; et al. (Peop. Rep. China ). Faming Zhuanli Shenqing Gongkai Shuomingshu CN 1044462 A 8 Aug 1990,7 pp. (People's Republic of China). CODEN: CNXXEV. CLASS: ICM: C07D213-68.Some commonly used reagents like 13603-44-6 and 7664-41-7 are used in this experiment. APPLICATION: CN 89-105390 26 Jan 1989. DOCUMENT TYPE: Patent CA Section: 27 (Heterocyclic Compounds (One Hetero Atom)) Section cross-reference(s): 5 The title compds. (I) is prepd. via ammonolysis of dehydroacetic acid (II) (using NH3 in an org. solvent, e.g., ethyleneglycol) and chlorination of 2,6-dimethyl-4-pyridinol (III) in an org. solvent. In this method the mother liquors from the ammonolysis and chlorination steps can be re-used. II in ethyleneglycol was reacted with 25% NH4OH at room temp. for 10 h to give III, whose aq. soln. was adjusted to pH 3 with concd. HCl, the aq. soln. was decolorized with activated charcoal, dild. with water, and then treated with Cl(g) at 0-5° to give 70% I of 98% purity. .

2,6-Dimethyl-4-pyridinol: 2,6-Dimethyl-4-pyridinol. Hruby, Milan; Ferenc, Milan (Czech. ). Czech. CS 162232 15 Feb 1976,3 pp. (Unavailable). (Czechoslovakia). CODEN: CZXXA9. CLASS: IC: C07D031-20. APPLICATION: CS 72-6655 2 Oct 1972.There are some reagents with their cas registry numbers 520-45-6 and 13603-44-6 are used in this study. DOCUMENT TYPE: Patent CA Section: 27 (Heterocyclic Compounds (One Hetero Atom)) Section cross-reference(s): 5 Dehydroacetic acid was heated with aq. NH4OH at 142-5.degree. in an autoclave with gradual discharge of CO2 and NH3 to maintain the pressure at 17-19 atm. to give a 6.24% soln. of the title compd. (4-lutidone) contaminated with 1-1.5% 4-lutidone-3-carboxylic acid (calcd. on the wt. of dry product). The soln. was used as such for the manuf. of the coccidiostatic drug 2,6-dimethyl-3,5-dichloro-4-pyridinol (clopidol) or pure 4-lutidone was crystd. in 77-94% yield. .
