Process for the preparation of 2-chloropyridines |
| abstract |
2-Chloropyridine derivatives of the formula (I) ##STR1## in which R represents hydrogen, C 1 -C 4 -alkyl or halogen and n n represents 0 to 4, n are obtained in good yields and high purity when a 2-aminopyridine derivative of the formula (II) ##STR2## in which R and n have the above definitions, n is reacted with nitrosyl chloride in a hydrogen chloride-saturated aqueous solution at temperatures between -10° C. and +50° C. with simultaneous introduction of hydrogen chloride. |
