Versuchsvorschrift

A mixture of pyridine-2,5-dicarboxylic acid (8.4 g), methanol (100 ml) and concentrated sulphuric acid (1.7 ml) was heated at reflux for 2 hours, cooled and poured into water (11). The resultant precipitate was collected and recrystallised from ethanol to give the title compound as a white solid, m.p. 222-223° C.
