    摘要: The present invention relates to 3-substituted and 2,3-disubstituted pyridine compounds which are useful as intermediates in the synthesis of pyridylsulfonylurea herbicides. The invention also relates to arylation of alcohols using a pyridinediazonium salt. More particularly the arylation process of the instant invention relates to the synthesis of 2,3-disubstituted pyridine compounds via anhydrous diazotization of 3-aminopyridines to form a diazonium salt intermediate that is then reacted with the appropriate alcohol to produce the desired product. The invention additionally relates to pyridine-3-diazonium salt intermediates.
