Procedure
A mixture of 4-chloro-2-mercaptobenzoic acid (6.00 g, 31.8 mmol), 2-cyanopyridine (1.90 g, 17.7 mmol) and pyridine (50.0 ml) was refluxed for 9 hrs as described in Example 9. After cooling, the precipitated crystals were collected by filtration and recrystallized from hexane-chlorobenzene to give the titled compound (2.30 g, 48%).
