| titleOfInvention | Process for the preparation of 2-chloropyridine |
| abstract | The present invention relates to a novel process for preparing 2-chloropyridine derivatives represented by formula (I), after dissolving pyridine 1-oxide in a general organic solvent, phosphoryl chloride, thionyl chloride, sulfonyl chloride, p- toluenesulfonyl Chlorinating agents such as chloride, benzenesulfonyl chloride, methanesulfonyl chloride and a method of preparing a compound of formula (I) by reacting in the presence of a base at a temperature below 0 ° C. to the boiling point of the solvent used. By addition of catalytic amount, the conversion rate and selectivity can be improved.n n n n n n n n (I)n n n The present invention can be produced in a high yield of the desired compound having excellent position selectivity by a simple reaction process using an inexpensive reactant can be expected excellent effect in industrial applicability. |
