Abstract
NEW MATERIAL:The substituted pyridine compound of formula I (R1 and R2 are H or alkyl; R is SH or SO2Cl) and its salt. EXAMPLE:2-Mercapto-N,N-dimethylnicotinamide. USE:A raw material for agricultural chemicals, pharmaceuticals, etc. Especially, an intermediate useful for the production of a pyridinesulfonamide herbicide on an industrial scale at a low cost. PREPARATION:A mercapto-substituted pyridine compound of formula I (R is SH) is produced by reacting a halogen-substituted pyridine compound of formula II (Hal is halogen) with a polysulfide of formula M2Sx (M is alkali metal elements; x is 2-8) and treating the reaction product with an acid. The product can be converted, as necessary, to a chlorosulfonyl-substituted pyridine compound of formula I (R is SO2Cl) by oxidization and chlorination.
