Versuchsvorschrift

A solution of 6 g (28.5 mmol) of 5-cyano-2-hydroxy-6-(methylthio)nicotinic acid in 35 ml of diphenyl ether is stirred at 250° C. for 4 hours. After returning to room temperature, 100 ml of cyclohexane is added and the reaction medium is triturated for 30 minutes. The solid formed is filtered, rinsed thoroughly with cyclohexane and then dried under vacuum to yield 2.87 g (60%) of 6-hydroxy-2-(methylthio)nicotinonitrile in the form of a brown powder.
