Procedure
A mixture of 2-mercaptoterephthalic acid (2.0 g, 10 mmol), 2-cyanopyridine (1.3 g, 11 mmol) and pyridine (10 ml) was refluxed for 8 hrs. After cooling, the precipitated crystals were collected by filtration and recrystallized from methanol-diisopropylether to give the titled compound (1.22 g, 42%).
