摘要:

4-Octyloxy-2,6-di(hydroxymethyl)pyridine(2), 4(4′-octyloxyphenyl)-2,6-di(hydroxymethyl)pyridine (4), and 4(4′-octadecyloxyphenyl)-2,6-di(hydroxymethyl)pyridine (3) were synthesised. By modification of a literature method the dimethyl (or ethyl) 4-hydroxypyridine-2,6-dicarboxylate (6) was synthesised with yield greater than 90%, using thionyl chloride/DMF catalyst mixture, compared with 55–85% using methanol or ethanol/H2SO4mixture as reported in literature.
