Versuchsvorschrift
By following the method of Examples 10-14, 4-picolyl mercaptan is reacted with 2-chloroethanol, 2-bromoethanol or ethylene oxide to yield 4-(2-hydroxyethylthiomethyl)pyridine, with 2-bromo-1-propanol to yield 4-(2-hydroxy-1-propylthiomethyl)-pyridine, with 1-chloro-2-propanol to yield 4-(1-hydroxy-2-propylthiomethyl) pyridine, with bromoacetaldehyde diethyl acetal (followed by acid catalyzed hydrolysis) to yield 4-picolylthioacetaldehyde, with 3-bromo-2-butanol to yield 4-(3-hydroxy-2-butylthiomethyl) pyridine, with ethyl 2-bromoacetate to yield ethyl 4-picolylthioacetate, with ethyl 2-chloropropionate to yield ethyl 2-(4-picolylthio)propionate and with methyl 2-phenyl-2-bromoacetate to yield methyl phenyl(4-picolylthio)acetate.
