Reaction Conditions

Reaction Steps

A mixture of 5.6 g (0.05 mole) of 2-mercaptopyridine, 3.3 g (0.05 mole) of potassium hydroxide (85% pellets), 35 ml of ethanol and 5 ml of water was prepared. To this mixture was added 7.8 g (0.05 mole) of 2,5-dimethyl-benzylchloride, while maintaining good stirring. The mixture was stirred and heated to 40° C. for 45 minutes, cooled to room temperature, and then added to 150 ml of water. The aqueous mixture was extracted with 150 ml of diethyl ether; the ether phase washed with 150 ml of water. Finally, the ether phase was dried with anhydrous sodium sulfate. Removal of the ether left a green oil. An infrared spectrum was consistent with the structure of 2-((2,5-dimethylphenyl)methylthio) pyridine.
