A mixture of 2-mercapto-4-methoxybenzoic acid (1.4 g, 7.9 mmol), 2-cyanopyridine (0.89 g, 8.5 mmol) and pyridine (10 ml) was refluxed for 10 hrs as described in Example 9. After cooling, the precipitated crystals were collected by filtration and recrystallized from hexane-tetrahydrofuran to give the titled compound (1.0 g, 47%) as crystals.
