Procedure
340.5 g (3 moles) 2-chloropyridine are added dropwise to a boiling solution of 375 g (3 moles) 2-mercaptoaniline in 1.8 liters 2-propanol with agitation and under an atmosphere of protective gas within 15 min. After termination of the addition, the mixture is agitated for 5 hours at boiling temperature. The mixture is then allowed to cool to room temperature, and the precipitated yellowish product is filtered off and washed twice with 50 ml 2-propanol per wash. After drying in a vacuum, 592 g (86% of theory), 2-(2-mercapto-phenylamino) pyridine is obtained as colorless to yellowish crystals.
