A number of 6-alkylthio(and sulfonyl)-substituted imidazo[1,2-a]pyridines were synthesized by the reaction of 5-alkylthio- and 5-alkylsulfonyl-2-aminopyridines with ?-bromoacetophenone and a-chlorocyclohexanone in order to search for new compounds that have fungicidal activity. 5-Alkylthio-2-aminopyridines were obtained from the double salt of 5-mercapto-2-aminopyridine with SnCl2 and HCl by reaction with alkyl halides or tert-C4H9OH and 75% H2SO4. 5-tert-Butylthio-2-aminopyridine was oxidized by means of KMnO4 to 5-tert-butylsulfonyl-2-aminopyridine. A double salt was synthesized from 2-aminopyridine-5-sulfonic acid. |
